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
