X² + x - 20 = 0
x² = x * x
x = the sum of the factors of -20
-20 ⇒ 1 x 20
2 x 10
- 4 x 5 ⇒ only these factors can arrive to a sum of 1
(x - 4)(x + 5) = x(x+5) - 4(x+5) = x² + 5x - 4x - 20 = x² + x - 20
x - 4 = 0
x = 4
x + 5 = 0
x = -5
Answer:
c- people might not realize there words/actions are hurtful
The factored form of a polynomial is comprised of factors in which the sum is equal to the coefficient of the second term and the product is equal to the coefficient of the third term. In this case, the factors of x2 + 3x - 4 = 0 are 4 and -1. hence the answer is B. <span>(x - 1)(x - 4) = 0</span>
