Solve for x. x2 + x - 6 = 0 a. -2, -3 b. -2, 3 c. 2, -3 d. 2, 3

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

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490
