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 ...

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 ...

Some quadratics cannot be factorised. An alternative method to solve a quadratic equation is to complete the square. To solve an equation of the form \(x^2 + bx + c = 0\) consider the expression ...
