Question

Find the product.
−4𝑥 (2𝑥² − 3𝑥 + 5)

hint Hint:

In multiplication of polynomials, multiply term with each other.
Identity: xa × xb = x(a+b)

The correct answer is: -8x3 + 12x2 - 20x.

Answer:

Step by step explanation:

Given:

      −4x (2x² - 3x + 5)

Step 1:

Multiplication:

(−4x × 2x²) + (−4x × -3x) + (−4x × 5)
$rightwards double arrow$ (-8x³) + (12x²) + (-20x)
$rightwards double arrow$ -8x³ + 12x² - 20x

Final Answer:

-8x³ + 12x² - 20x.
