Question analysis
This question asks us to factorise and solve an equation. So we need to put the expression into brackets first. Now, the first thing we should always check is the highest common factor. Keep in mind that to complete the square (which we'll need to do in this case), we always need to take out the coefficient of \(x^2\) as a common factor.
In part (b). we can use the null factor law once we have done part (a) to solve the equation.
