- 5 x^{2} - 90 x = - 555

x = - 9 - 83, x = 83 - 9

Decimal Notation

x = - 22.85640 \dots, x = 4.85640 \dots

Solution steps

- 5 x^{2} - 90 x = - 555

Move

555

to the left side

- 5 x^{2} - 90 x + 555 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 90 ) \pm ( - 90 ) ^{2} - 4 ( - 5 ) \cdot 555}{2 ( - 5 )}

(- 90)^{2} - 4 (- 5) \cdot 555 = 803

x_{1, 2} = \frac{- ( - 90 ) \pm 80 3}{2 ( - 5 )}

Separate the solutions

x_{1} = \frac{- ( - 90 ) + 80 3}{2 ( - 5 )}, x_{2} = \frac{- ( - 90 ) - 80 3}{2 ( - 5 )}

x = \frac{- ( - 90 ) + 80 3}{2 ( - 5 )} : - 9 - 83

x = \frac{- ( - 90 ) - 80 3}{2 ( - 5 )} : 83 - 9

The solutions to the quadratic equation are:

x = - 9 - 83, x = 83 - 9

x, 5 x^{2} - 12 y^{2} + 3 x y^{2} = 10

x^{2} = - 15

(3 p + 2)^{2} = 8

a^{2} = 8

- p^{2} + 6 p + 14 = 3 p^{2}
