Which unit tiles are needed to complete the
factorization?
O 2 negative unit tiles
2 positive unit tiles
O 5 negative unit tiles
O 5 positive unit tiles

x² - 3x - 10

x² = x * x

10 can be factored:

1 x 10 ⇒⇒⇒ difference between factors = 9

2 x 5   ⇒⇒⇒ difference between factors = 3  ⇒ (The correct pair)

(x-5)(x+2) = x(x+2) - 5(x+2)

                = x² + 2x - 5x - 10

                = x² - 3x - 10

x - 5 = 0  ⇒⇒⇒ x = 5

  x + 2 = 0  ⇒⇒⇒ x = -2

0/5 is 0, 2/0 is undefined, and 0/0 is indeterminate.
