The function y=x^2+x-6 is graphed

- what are the values/roots/ solutions when

x^2+x-6=-4

a) x=-4 and 6 d) x=-3 and 2

b) x=-2 and 1 e) x=-5 and -6

We want to solve this equation for x.

x^{2} + x - 6 = -4

Add 4 to both sides.

x^{2} + x - 2 = 0

Factor.

(x + 2)(x - 1) = 0

Set each factor = 0 and solve for x.

x + 2 = 0 and x - 1 = 0

x = -2 and x = 1

Which is b)

Thx @hectictar this assignment is practice for my STARR so I appreciate the help.

(I may keep asking other questions so stay alert brp)
