AQA All About Maths - Equations

In order to learn how to solve quadratic equations by four different methods, please follow this tutorial ; it's detailed and offers plenty of worked examples and practice questions. In this tutorial, I assume you have already got a good skill in solving quadratic equations as explained in the above tutorial. This tutorial primarily focuses on solving real-world problems involving quadratic equations.

If you think you need a bit more practice before dealing with word problems, here is a question generator and a programme to check your answers:. The following programme is interactive: by clicking on the buttons, you can generate a random equation and its solutions: they are randomly generated - and unlimited in number. The book covers every single topic in depth and offers plenty of questions to practise.

The questions progress well so that students can get a good conceptual understanding of every major topic. A disciplined practice through this book prepares the students for both examinations fully. There is enough coverage on new additions to the syllabus with a significant amount of questions. The sum of two numbers is 27 and their product is Find the numbers. Let one Equations For Maths Gcse Aqa number be x. The length of a rectangle is 5 cm more than its width and the area is 50cm 2.

Find the length, width and the perimeter. Let the width be x. Find x and the skiff building plans free time, if the longest side is 5. The product of two numbers is 24 and the mean is 5. The sum of numbers is 9. The squares of the numbers is These are quadratic simultaneous equations. There are quite a few real life situations that can be modelled by a quadratic function in skiff building plans free time accurate way.

For instance, the motion of a ball, thrown upwards to move under gravity, can be easily modelled by a quadratic equation. Using the model, we can calculate the height of the ball if the time is known or vice versa. A ball is thrown upwards from a rooftop, 80m above the ground. It will reach a maximum vertical height and then fall back to the ground.

A farmer wants to make a rectangular pen for his sheep. He has 60m fencing material to cover three sides with the other side being a brick wall. How should he use the fencing material to maximize the space for his sheep?

How should he choose length and width of the pen to achieve his objective? He just has to cover three sides; let the width be x. Which is as follows:. A very useful way to use quadratic equations in real equations for maths gcse aqa quarterindeed!

Two resistors, when connected in series, have a total resistance of 25 Ohms. If they are connected in parallel, the value goes down skiff building plans free time 6 Ohms. Find the values. The following picture shows the shape of a certain grass patch.

If the area of the patch is 80m 2find k. The following picture shows the shape of a rectangle from which a smaller rectangular part is removed. If the remaining area of the larger rectangle is 35cm 2find k. The shortest side of a right-angled triangle is 6cm shorter than its hypotenuse.

The difference in length of other two sides is 3cm. Hence, find n. Two cyclists move away from a town along two perpendicular paths at 20 mph and 40 mph respectively. The second cyclist equations for maths gcse aqa quarter the journey an hour later than the first one. Find the time taken for them to be skiff building plans free time apart.

With the available data, the stopping distance - sum of thinking distance and breaking distance - can be modelled by a quadratic function. It is as follows:. The following animation shows how the stopping distance, modelled by the above equation, changes with the speed:. So, the value of the above infinite square problem is 5. The questions, however, are superb for anyone who want to master mathematical concepts in this age group, regardless of the examinations that they sit.

The book contains lots of exercises, graded progressively from simple to harder, covering almost all the topics. If they are practised in the order given, the confidence of the students are naturally boosted to such an extent the need for any more resources becomes non-existent. There are two books in this skiff building plans free time - book one and book two.

I strongly recommend both for students. Please click the image, which will take you to Amazon book store. Ad: The author of this site offers fully interactive tutorial on differentiation. Now, in order to complement what you have just learnt, work out the following questions:. Do you need detailed solutions to the above questions? Please equations for maths gcse aqa quarter the following and I will send the answers:.
