- 5 x^{2} - 80 x - 1545 = 0

x = - 8 - 75 i, x = - 8 + 75 i

Solution steps

- 5 x^{2} - 80 x - 1545 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 ( - 5 ) ( - 1545 )}{2 ( - 5 )}

Simplify

(- 80)^{2} - 4 (- 5) (- 1545) : 705 i

x_{1, 2} = \frac{- ( - 80 ) \pm 70 5 i}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 80 ) + 70 5 i}{2 ( - 5 )}, x_{2} = \frac{- ( - 80 ) - 70 5 i}{2 ( - 5 )}

x = \frac{- ( - 80 ) + 70 5 i}{2 ( - 5 )} : - 8 - 75 i

x = \frac{- ( - 80 ) - 70 5 i}{2 ( - 5 )} : - 8 + 75 i

The solutions to the quadratic equation are:

x = - 8 - 75 i, x = - 8 + 75 i

- 3 x^{2} + 6 x = - 321

300 = 18 x^{2} - 180 x - 3300

- 0.05 x^{2} + 16 x + 80 = 0

x, z = - x^{2} - y^{2}

x^{2} - (3 + 1) x + 3 = 0
