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)

Find the square (5p-9)(5p-9)
Hunter-Best [27]

Answer:

The square would be 25p^2 - 90p + 81

Step-by-step explanation:

To get this, use the FOIL method. In this, we multiply the first, outer, inner and last pairings.

First - Multiply the first number in each parenthesis.

5p * 5p = 25p^2

Outer - Multiply the outside numbers in each parenthesis.

5p * -9 = -45p

Inner - Multiply the inner numbers in each parenthesis.

-9 * 5p = -45p

Last = Multiply the last numbers in each parenthesis

-9 * -9 = 81

Now take all of those numbers and add together. Then simplify.

25p^2 - 45p - 45p + 81

25p^2 - 90p + 81
