Factor the following:

x2−x−20

Question 9 options:

(x−4)(x−5)

(x−5)(x+4)

(x−4)(x+5)

(x+1)(x−20)

(x + 4) (x - 5) so B:

Step-by-step explanation:

Factor the following:

x^2 - x - 20

The factors of -20 that sum to -1 are 4 and -5. So, x^2 - x - 20 = (x + 4) (x - 5):

(x + 4) (x - 5)

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
