We know that the normal goes through the points (0, 0) and (3, 4) so we can calculate the gradient: \frac 4y=-3x+25 Looking for more algebra questions and resources? To work out the gradient of the line we need to work out the gradient of the normal. When working with algebraic expressions and equations we must consider carefully which operations to deal with first. Brackets, Indices (powers, exponents, square roots), Division, Multiplication, Addition, Subtraction. Remember, when working with algebra, we must still apply BODMAS / BIDMAS. i.e. ![]() Make x the subject – rewrite the equation in the form x =….Expand brackets – multiply out the brackets. ![]() Simplify – collect together like terms to make the expression or equation look simpler.Substitute – put the values you have been given into the algebraic expression.Solve the equation – find out the value of the unknown.Here are some of the key terms along with what they mean: When you are presented with an algebraic problem it is important to establish what you are being asked to do. In KS4 we develop these techniques to allow us to deal with more complicated algebra problems such as ones that involve quadratic equations or a system of equations. In KS3 we learn to write and manipulate basic algebraic expressions and linear equations. There are many topics and techniques within algebra. – GCSE maths questions Algebra in KS3 and KS4 In addition to the GCSE maths tuition we provide to secondary schools more support is available free for GCSE maths revision including: Looking for more KS3 and KS4 maths questions?įree GCSE maths revision resources for schools.Looking for more algebra questions and resources?.Algebra questions KS4: forming and solving equations.Algebra questions KS4: algebraic manipulation.Algebra questions KS3: forming and solving equations. ![]()
