x^{2}=-6-10
Subtract 10 from both sides.
x^{2}=-16
Subtract 10 from -6 to get -16.
x=4i x=-4i
The equation is now solved.
x^{2}+10+6=0
Add 6 to both sides.
x^{2}+16=0
Add 10 and 6 to get 16.
x=\frac{0±\sqrt{0^{2}-4\times 16}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 16 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±\sqrt{-4\times 16}}{2}
Square 0.
x=\frac{0±\sqrt{-64}}{2}
Multiply -4 times 16.
x=\frac{0±8i}{2}
Take the square root of -64.
x=4i
Now solve the equation x=\frac{0±8i}{2} when ± is plus.
x=-4i
Now solve the equation x=\frac{0±8i}{2} when ± is minus.
x=4i x=-4i
The equation is now solved.
