solve the equation |2x+ 4| = 8

a. x=-12 or x=4
b. x= -6 or x=2
c. x= 2 only
d. x - 6 only

b. x= -6 or x=2

Step-by-step explanation:

|2x+ 4| = 8

The absolute value equation has 2 solutions, one positive and one negative

2x+4 = 8           2x+4 = -8

Subtract 4 from each side

2x+4-4 = 8-4      2x+4-4 = -8-4

2x = 4                  2x = -12

2x/2 =4/2              2x/2 = -12/2

x =2                      x = -6

a - base

b - exponent

so,
