Question

Solve 5x^2 = -30x - 65

Answer 1

x = -3 +/- 2i

x = -3 +/- 4i

x = -6+/- 2i

x = -6 +/- 4i

Answer 2

Transpose your 5x² = -30x - 65
0 = 5x² - 30x - 65

Now you need to solve the binomial.

Answer 3

you can take out 5 giving
5(x^2 + 6x + 13) = 0

this won't factor so you need to use quadratic formula to solve it

Answer 4

x = [ -6 +/- sqrt(6^2 - 4*13)] / 2
