So the solutions of the equation are \({x}\) = -2 and \({x}\) = -7. Where the graph crosses the line \({y}\) = 0 we will have our solutions. As the graph is quadratic we can see that the line ...

An animated guide to factorising quadratic expressions and equations. Examples are used to show how to find factors that multiply to give the number term and add to give the x coefficient in an ...

Everyone learns (and some readers maybe still remember) the quadratic formula. It’s a pillar of algebra and allows you to solve equations like Ax 2 +Bx+C=0. But just because you’ve used it ...

quadratic equations, polynomial expressions and equations, rational expressions and equations, roots and radicals, and exponential & logarithmic properties and equations. Note: Students who have ...
