Now try the example question below. Solve the quadratic equation \({x^2} - 6x + 8\) by completing the table below, plotting the points and drawing the parabola then reading off the roots from the ...

Before we look at the new solution, let’s talk about ... The only real problem is not many quadratic equations have A=1. For example, suppose you throw a ball straight up from 5 meters above ...

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 ...
