Solve x^2+14^2=0

$$x ^ { 2 } + 14 ^ { 2 } = 0$$

Solve for x (complex solution)

$$x=-14i$$

$$x=14i$$

Steps by Finding Square Root

Calculate 14 to the power of 2 and get 196.

$$x^{2}+196=0$$

Subtract 196 from both sides. Anything subtracted from zero gives its negation.

$$x^{2}=-196$$

The equation is now solved.

$$x=14i x=-14i$$

Steps Using the Quadratic Formula

Calculate 14 to the power of 2 and get 196.

$$x^{2}+196=0$$

This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 196 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.

$$x=\frac{0±\sqrt{0^{2}-4\times 196}}{2}$$

Square 0.

$$x=\frac{0±\sqrt{-4\times 196}}{2}$$

Multiply -4 times 196.

$$x=\frac{0±\sqrt{-784}}{2}$$

Take the square root of -784.

$$x=\frac{0±28i}{2}$$

Now solve the equation x=\frac{0±28i}{2} when ± is plus.

$$x=14i$$

Now solve the equation x=\frac{0±28i}{2} when ± is minus.

$$x=-14i$$

The equation is now solved.

$$x=14i x=-14i$$
