What is the solution set of x^2 - 10 = 30x

x^2-30x-10=0

Use the quadratic formula

-b +or- square root of b^2 -4ac all divided by 2a

a = 1       b = -30      c = -10

30 +or- square root of (30)^2-4(-10) all divided by 2

(30+sqrt940)/2

x=30.33

(30-sqrt940)/2

x=-0.33

The solution is x=-0.33 and 30.33
