x^{2} - 45 x - 900 = 0

x = 60, x = - 15

Solution steps

x^{2} - 45 x - 900 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 45 ) \pm ( - 45 ) ^{2} - 4 \cdot 1 \cdot ( - 900 )}{2 \cdot 1}

(- 45)^{2} - 4 \cdot 1 \cdot (- 900) = 75

x_{1, 2} = \frac{- ( - 45 ) \pm 75}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 45 ) + 75}{2 \cdot 1}, x_{2} = \frac{- ( - 45 ) - 75}{2 \cdot 1}

x = \frac{- ( - 45 ) + 75}{2 \cdot 1} : 60

x = \frac{- ( - 45 ) - 75}{2 \cdot 1} : - 15

The solutions to the quadratic equation are:

x = 60, x = - 15

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