Question

solve the quadratic equation X ² - X - 6 = 0​

Answer 1

Answer:

factors are -2 and 3

Explanation:

x² - x - 6

x² - (3 - 2)x - 6

x² - 3x + 2x - 6

x(x - 3).+2(x - 3)

(x + 2)(x - 3)

x + 2 = 0 , x - 3 = 0

x = -2 , x = 3

Answer 2

Answer:

X2-x-6=0

X2+3x-2x-6=0

X(x+3)-2(x+3)=0

(X-2)(x+3)=0

X=2 and x =-3
