Question

Solve each equation by graphing. Round to the nearest tenth.
-2x^2+2=-3x

Answer 1

x = -0.5 or x = 2

Explanation:

Finding solutions graphically is often easier if the equation can be put in the form f(x) = 0. Here, we can do that by subtracting the right-side expression to give ...

(-2x^2 +2) -(-3x) = 0

This could be put in standard form, but there is no need. A graphing calculator can deal with this directly.

The solutions are x = -0.5 and x = 2.
