The answer is no real solution

Step-by-step explanation:

Let's solve your equation step-by-step.

3x2=−12x−15

Step 1: Subtract -12x-15 from both sides.

3x2−(−12x−15)=−12x−15−(−12x−15)

3x2+12x+15=0

Step 2: Use quadratic formula with a=3, b=12, c=15.

x=

−b±√b2−4ac

2a

x=

−(12)±√(12)2−4(3)(15)

2(3)

x=

−12±√−36
