Multiply (5x2 – 3x)(8x2 + 4x)
O A. 40A - 4x3 – 12x2
OB. 40x4 – 24xhing 12x2
C. 40x4 - 24x2 - 12x
O D. 40x4 - 4x2 - 12x

When you multiply (5x² - 3x)(8x²+ 4x), then you will get 40x⁴ - 4x³ - 12x²

Step-by-step explanation:

(5x² - 3x)(8x² + 4x)

Multiply 5x² to (8x² + 4x) and multiply -3x to (8x² + 4x).

40x⁴ + 20x³ - 24x³ - 12x²

Combine like terms and don't forget to put the equation in standard form. This means that the exponents are going to be in descending order.

40x⁴ - 4x³ - 12x²

So, your answer will be letter choice A.
