Question

Use the quadratic formula to solve the equation.
x^2-7x-6=0

Answer 1

\[- b \pm \sqrt{\frac{ b^2-4ac }{ 2a }}\]
a=1, b=-7,c=-6.
\[-(-7) \pm \sqrt{\frac{ (-7^2-4(1)(-6) }{ 2(1) }}\]
\[7 \pm \sqrt{\frac{ 49+24 }{ 2 }}\]
\[7 \pm \sqrt{\frac{73}{2}}\]
\[x=7 + \sqrt{26.5}\]
and
\[x=7-\sqrt{26.5}\]
