M 2 m -2 Below is the graph of the expression in the left side of the given equation for m 2 and m -2. The equation has two solutions which may be identical or different. In earlier classes you read about the quadratic equations.
Set them equal to each other.
X a x b x2 2 a b ab. Note that in each case the graph has 1 x intercept only hence one real solution to the equation. There are other methods of finding the solutions of quadratic equations too such as factoring. Graphically by plotting them both on the Function Grapher and zooming in.
