Use the distributive property: a (b + c) = ab + ac

(3x² + 2x - 5) (2x - 3) = 3x² (2x - 3) + 2x (2x - 3) - 5 (2x - 3)

... = (6x³ - 9x²) + (4x² - 6x) + (-10x + 15)

... = 6x³ - 5x² - 16x + 15

Answer:

15

Step-by-step explanation:

If CD and DE equal, then x+6 = 4x -21

So if you subtract x from both sides and plus 21 to both sides, that would be 3x = 27. Divide by 3 on both sides and you get 9.

Plug in x+6 with 9 and you get 15.
