5 x^{2} - 25 x - 180 = 0

x = 9, x = - 4

Solution steps

5 x^{2} - 25 x - 180 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 25 ) \pm ( - 25 ) ^{2} - 4 \cdot 5 ( - 180 )}{2 \cdot 5}

(- 25)^{2} - 4 \cdot 5 (- 180) = 65

x_{1, 2} = \frac{- ( - 25 ) \pm 65}{2 \cdot 5}

Separate the solutions

x_{1} = \frac{- ( - 25 ) + 65}{2 \cdot 5}, x_{2} = \frac{- ( - 25 ) - 65}{2 \cdot 5}

x = \frac{- ( - 25 ) + 65}{2 \cdot 5} : 9

x = \frac{- ( - 25 ) - 65}{2 \cdot 5} : - 4

The solutions to the quadratic equation are:

x = 9, x = - 4

(s + 1)^{2} = 0

3 x^{2} + 6 x + 12 = 0

x^{2} - 17 x + 50 = - 2 x

- 2 x^{2} - 10 x - 12 = 0

z^{2} + 2 z + 1 = 0
