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

I have attached algebra tiles for the given equation.

step-by-step explanation:

2*5=10

4*15=60

60+10=

these sign is used to tell weather the number is greater or less than the number   <   or >     but this sign means its equal =
