Find all solutions to the equation $x^2 - 7x = 30$.
If you find more than one, then list the values separated by commas. If the solutions are not real, then they should be written in $a + bi$ form.
x2 -7x - 30 = 0 Use Quadratic Formula a = 1 b = -7 c = -30
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\) you will find x = 10 and -3
(x-10)(x+3) = x^2 -7x-30 check !
