\(2x^2 – 7x – 4\) factorises as \((2x + 1)(x – 4)\). \((2x + 1)(x – 4) = 0\). \(2x + 1 = 0 \) means \(x = -\frac{1}{2}\). \(x – 4 = 0\) means \(x = 4 ...

If a quadratic equation can be factorised, the factors can be used to find the roots of the equation. The equation factorises to give \((x + 3) (x - 2) = 0 \) so the solutions to the equation \(x^2 + ...
