Answer 1

Hi,

[(-5, 0), (-1, 0)]

Answer 2

@Compassionate , thank you.

Answer 3

−3|2x + 6| = −12

Divide both sides by -3

|2x + 6| = 4

Subtract 6 from both sides,

2x = -2
/2 /2

x = -1

Now make a new equation except with the answer being negative,

|2x + 6| = -4
-6 -6

2x = -10
/2 /2

x = -5

(-1,0) & (-5,0)
