Answer: $x+\frac{b}{2a}=\pm \frac{\sqrt{b^2 - 4ac}}{\sqrt{4a^2}}$

Step-by-step explanation:

We can rewrite the left hand side as a perfect square, more specifically

$\left(x+\frac{b}{2a} \right)^2$

So, taking the square root of both sides,

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