Answer:

x=-5/3 or x=-1/2

Step-by-step explanation:

1: Simplify both sides of the equation.

36x2+60x+15=−18x−15

2: Subtract -18x-15 from both sides.

36x2+60x+15−(−18x−15)=−18x−15−(−18x−15)

36x2+78x+30=0

3: Factor left side of equation.

6(3x+5)(2x+1)=0

4: Set factors equal to 0.

3x+5=0 or 2x+1=0
