Step 1

1 of 2We will use completing the square method:

$\begin{align}\begin{split} x^2-14x-736 &= 0 \\ x^2-14x &= 736 \\ x^2-14x+49 &= 736+49 \\ (x-7)^2 &= 785 \\ x-7 &= \pm \sqrt{785} \\ x&= 7\pm \sqrt{785} \end{split}\end{align}$

thus solutions of quadratic equation are $7+ \sqrt{785}$ and $7- \sqrt{785}$.
