Which of the following is the solution to | x +11k 17 ? A. X < 6 and x < -28
B. X<60rx>-28
C. x< 6 and xx -28
D. x <6

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

multiply then divide
