- 3 x^{2} + 30 x - 90 = 0

x = 5 - 5 i, x = 5 + 5 i

Solution steps

- 3 x^{2} + 30 x - 90 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 ( - 3 ) ( - 90 )}{2 ( - 3 )}

Simplify

3 0^{2} - 4 (- 3) (- 90) : 65 i

x_{1, 2} = \frac{- 30 \pm 6 5 i}{2 ( - 3 )}

Separate the solutions

x_{1} = \frac{- 30 + 6 5 i}{2 ( - 3 )}, x_{2} = \frac{- 30 - 6 5 i}{2 ( - 3 )}

x = \frac{- 30 + 6 5 i}{2 ( - 3 )} : 5 - 5 i

x = \frac{- 30 - 6 5 i}{2 ( - 3 )} : 5 + 5 i

The solutions to the quadratic equation are:

x = 5 - 5 i, x = 5 + 5 i

3 p^{2} - 35 p - 12

2 x = \frac{4}{3}

(x - 9)^{2} = - 5

\frac{x ^{- 8}}{x ^{- 5}}

- 3 (1 - 6 x) = 18 - 3 x
