Quadratic Equations (Easy)

Algebra Level 1

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

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

\[ x^2−20x−69=0.\]

\(\sqrt{31}-10\), \( -\big(\sqrt{31}+10\big)\) \(\frac { \sqrt{4681}-69}{2}\), \(\frac{-\sqrt{4681}+69}{2}\) \(\frac{\sqrt{4841}+69}{2}\), \(\frac{-\big(\sqrt{4841}-69\big)}{2}\) \[23,-3\]
