- 5 x^{2} - 90 x - 765 = 0

x = - 9 - 62 i, x = - 9 + 62 i

Solution steps

- 5 x^{2} - 90 x - 765 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 90 ) \pm ( - 90 ) ^{2} - 4 ( - 5 ) ( - 765 )}{2 ( - 5 )}

Simplify

(- 90)^{2} - 4 (- 5) (- 765) : 602 i

x_{1, 2} = \frac{- ( - 90 ) \pm 60 2 i}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 90 ) + 60 2 i}{2 ( - 5 )}, x_{2} = \frac{- ( - 90 ) - 60 2 i}{2 ( - 5 )}

x = \frac{- ( - 90 ) + 60 2 i}{2 ( - 5 )} : - 9 - 62 i

x = \frac{- ( - 90 ) - 60 2 i}{2 ( - 5 )} : - 9 + 62 i

The solutions to the quadratic equation are:

x = - 9 - 62 i, x = - 9 + 62 i

2 x - 3 x^{2} = 5

3 v^{2} + 18 v = 0

2 x^{2} - 21 x + 49 = 0

3 x^{2} + x = 400

10 x + 18 + 2 x^{2} + 2 = 4 x^{2} + 28
