Answer:

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.
