- 5 x^{2} - 80 x - 330 = 0

x = - 8 - 2 i, x = - 8 + 2 i

Solution steps

- 5 x^{2} - 80 x - 330 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 ( - 5 ) ( - 330 )}{2 ( - 5 )}

Simplify

(- 80)^{2} - 4 (- 5) (- 330) : 102 i

x_{1, 2} = \frac{- ( - 80 ) \pm 10 2 i}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 80 ) + 10 2 i}{2 ( - 5 )}, x_{2} = \frac{- ( - 80 ) - 10 2 i}{2 ( - 5 )}

x = \frac{- ( - 80 ) + 10 2 i}{2 ( - 5 )} : - 8 - 2 i

x = \frac{- ( - 80 ) - 10 2 i}{2 ( - 5 )} : - 8 + 2 i

The solutions to the quadratic equation are:

x = - 8 - 2 i, x = - 8 + 2 i

x^{2} + 2 x + 64 = 0

\frac{5}{7} x^{2} = 0

x^{2} - 16 x + 64 = 0

x^{2} - 20 = 5

s^{2} + 4 s + 4
