Solve for x. x2 + x - 6 = 0 A. -2, -3 B. -2, 3 C. 2, -3 D. 2, 3
2 answers:
Factor x^2 + x - 6
(x - 2)(x + 3) = 0
Solve for x
Ask yourself; When will (x - 2)(x + 3) equal zero?
When x - 2 = 0 or x + 3 = 0
Then solve for each of the two equations above
<em>x = 2, -3</em>
<u>Answer: C. 2, -3</u>
Answer:
C. 2, -3
Step-by-step explanation:
x^2 + x - 6 = 0
Factor
What 2 numbers multiply to -6 and add to 1
3*-2 =6
3-2 =1
(x+3) (x-2) =0
Using the zero product property
x+3 = 0 x-2 =0
x+3-3= 0-3 x-2+2 =0+2
x = -3 x =2
