Answer:
2x(x + 5)(x - 2y)
Step-by-step explanation:
Given
2x³ + 10x² - 4x²y - 20xy ← factor out 2x from each term
= 2x(x² + 5x - 2xy - 10y)
Factor the first/second and third/fourth terms inside the parenthesis
= 2x(x(x + 5) - 2y(x + 5)) ← factor out (x + 5) from each term in the parenthesis
= 2x(x + 5)(x - 2y)
