Simplify and expand (5x+2) (2x-3)

The answer is 10x² - 11x - 6.

Step-by-step explanation:

Firstly, you have to get rid of brackets by expanding:

(5x+2) (2x-3)

= 5x (2x) + 5x (-3) + 2 (2x) + 2 (-3)

= 10x² - 15x + 4x - 6

Next, you have to simplify by putting all the common/like term together:

10x² - 15x + 4x - 6

= 10x² - 11x - 6
