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

  • B: 7/12=21/36. 5/6=25/36. 17/18=34.
  • C: 11/12=33/36. 5/6=25/36. 31/36=31/36.
  • D: 1/4=6/24. 5/6=20/24. 5/8=15/24.

Out of A, B, C, and D– only B works.
