3x(x + 6) = -10

Answer: See below

Step-by-step explanation:

To find the solution, we must first expand 3x(x+6) and move all terms onto one side.

3x²+18x=-10

3x²+18x+10=0

Since this equation is hard to factor, we will use the quadratic formula to get the solutions.

We know our values of A, B, C to plug into the quadratic equation.

A=3

B=18

C=10

\frac{-b±\sqrt{b^{2} -4ac} }{2a}

(Ignore the capital A in the equation. It pops up when I use the ± sign.)

After you plug in the values of A, B, C into the equation, you get:

x=\frac{-9+\sqrt{51} }{3} and x=-\frac{9+\sqrt{51}  }{3}
