Question

What are the factors of x2 – 100? (x – 50)(x 50) (x – 10)(x 10) (x – 25)(x 4) (x – 5)(x 20)

Answer 1

Answer:

(x + 10)(x - 10)

Step-by-step explanation:

x² - 100 = x² - 10²

This is a difference of two squares.

A difference of wo squares follows this pattern for factoring:

a² - b² = (a + b)(a - b)

We have

x² - 10² = (x + 10)(x - 10)

Answer 2
