Quadratic Equations (Easy)

Algebra

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

Using the quadratic formula above, find the roots of the equation

$x^2-20x-69=0.$

\frac{\sqrt{4841}+69}{2}

\frac{-\big(\sqrt{4841}-69\big)}{2}

\frac { \sqrt{4681}-69}{2}

\frac{-\sqrt{4681}+69}{2}

23,-3

\sqrt{31}-10

-\big(\sqrt{31}+10\big)
