Question

Multiply.
-2x (-5x² + 3x²-8x + 7)

Answer 1

To multiply -2x by the expression (-5x² + 3x² - 8x + 7), we can use the distributive property:

-2x (-5x² + 3x² - 8x + 7)

= (-2x)×(-5x²) + (-2x)×(3x²) + (-2x)×(-8x) + (-2x)×(7)

= 10x³ - 6x³ + 16x² - 14x

Therefore, the product is:

10x³ - 6x³ + 16x² - 14x

= 4x³ + 16x² - 14x

So the final answer is 4x³ + 16x² - 14x.
