Solve the quadratic equations given. Simplify each result. $$x^{2}=-2 x-19$$
Added by Lisa M.
Step 1
Substituting these values into the formula, we get: $$x=\frac{-2\pm\sqrt{2^{2}-4(1)(19)}}{2(1)}$$ Simplifying under the square root: $$x=\frac{-2\pm\sqrt{-72}}{2}$$ Since the square root of a negative number is not a real number, we cannot simplify this any Show more…
