Expand and simplify (3x+2) ^2 - (2x-1) ^2

If you would like to calculate (3 * x + 2) ^2 - (2 * x - 1) ^2, you can do this using the following steps:

(3 * x + 2) ^2 - (2 * x - 1) ^2 =

9 * x^2 + 12 * x + 4 - (4 * x^2 - 4 * x + 1) =

9 * x^2 + 12 * x + 4 - 4 * x^2 + 4 * x - 1 =

5 * x^2 + 16 * x + 3

The result is 5 * x^2 + 16 * x + 3.
