Question

how do you find the roots using the quadratic of x^2+7x-7

Answer 1

Do you know the quadratic formula?

Answer 2

(-b+-sqrt(b^2-(4 *a*c))/(2*a);
(-7+-sqrt(49-(-28))/2;
(-7+-sqrt(77))/2
x=(-7+sqrt(77))/2 and (-7- sqrt(77))/2

Answer 3

\[x=\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}\]
And plug in a=1, b=7, c=-7.
