Solve for x.

xenn [34]

Answer:

$a \: \: x = \frac{ -1 ± i\sqrt{139}}{14}$

Explanation:

Since this is unfactorable, use the Quadratic Formula:

$x = -b ± \frac{ \sqrt{ {b}^{2} - 4ac}}{2a}$

Now, take the information and input it:

$-1 ± \frac{ \sqrt{1 - 4(7)(5)}}{2(7)} \\ \\ -1 ± \frac{ \sqrt{ -139}}{ 14} = \frac{-1 ± i\sqrt{139}}{14}$

I am joyous to assist you anytime.
