In this question we are looking for a solution to x where the equation will equal to 0.We can first try factorising this, in the framework: (x+a)(x+b). Remembering the method of FOILS (first, outer, inner...
In order to find the coefficient we need to know which term of the binomial expansion is constant. We know the expression to find the coefficient is (8Cn)(2^n)((1/4)^(8-n)), where n is the power ...
The above sample question was taken from the 2018 GCSE Maths Higher paper.First we simplify the numerator, 3x^2 - 8x - 3, which is a quadratic written in the form ax^2 + bx + c so we can simplify it by fa...
2x2+7x+6=0First this question is asking you to find out what x is, but to do that we need to factorise this equation.Find all the factors that multiply to make 6.3 and 2, 6 and 1Of these factor...
The turning point can be found by using the concept of transformations. Firstly, it is important to form a relation between the values of a and b in an equation of the following form y = (x+a)^2 + b and t...
