Solve by factoring out GCF
πLearn how to solve a quadratic equation by factoring out the GCF. When factoring out the gcf from an equation we will be looking for what the terms have in common. This method is very useful for ...
\(2x^2 β 7x β 4\) factorises as \((2x + 1)(x β 4)\). \((2x + 1)(x β 4) = 0\). \(2x + 1 = 0 \) means \(x = -\frac{1}{2}\). \(x β 4 = 0\) 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 + ...
