-x^{2}+2x+3=2\left(x+3\right)
Variable x cannot be equal to -3 since division by zero is not defined. Multiply both sides of the equation by x+3.
-x^{2}+2x+3=2x+6
Use the distributive property to multiply 2 by x+3.
-x^{2}+2x+3-2x=6
Subtract 2x from both sides.
-x^{2}+3=6
Combine 2x and -2x to get 0.
-x^{2}=6-3
Subtract 3 from both sides.
-x^{2}=3
Subtract 3 from 6 to get 3.
x^{2}=-3
Divide both sides by -1.
x=\sqrt{3}i x=-\sqrt{3}i
The equation is now solved.
-x^{2}+2x+3=2\left(x+3\right)
Variable x cannot be equal to -3 since division by zero is not defined. Multiply both sides of the equation by x+3.
-x^{2}+2x+3=2x+6
Use the distributive property to multiply 2 by x+3.
-x^{2}+2x+3-2x=6
Subtract 2x from both sides.
-x^{2}+3=6
Combine 2x and -2x to get 0.
-x^{2}+3-6=0
Subtract 6 from both sides.
-x^{2}-3=0
Subtract 6 from 3 to get -3.
x=\frac{0±\sqrt{0^{2}-4\left(-1\right)\left(-3\right)}}{2\left(-1\right)}
This equation is in standard form: ax^{2}+bx+c=0. Substitute -1 for a, 0 for b, and -3 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\left(-1\right)\left(-3\right)}}{2\left(-1\right)}
Square 0.
x=\frac{0±\sqrt{4\left(-3\right)}}{2\left(-1\right)}
Multiply -4 times -1.
x=\frac{0±\sqrt{-12}}{2\left(-1\right)}
Multiply 4 times -3.
x=\frac{0±2\sqrt{3}i}{2\left(-1\right)}
Take the square root of -12.
x=\frac{0±2\sqrt{3}i}{-2}
Multiply 2 times -1.
x=-\sqrt{3}i
Now solve the equation x=\frac{0±2\sqrt{3}i}{-2} when ± is plus.
x=\sqrt{3}i
Now solve the equation x=\frac{0±2\sqrt{3}i}{-2} when ± is minus.
x=-\sqrt{3}i x=\sqrt{3}i
The equation is now solved.
