x^{2} - 80 x - 900 = 0

x = 90, x = - 10

Solution steps

x^{2} - 80 x - 900 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 80 ) \pm ( - 80 ) ^{2} - 4 \cdot 1 \cdot ( - 900 )}{2 \cdot 1}

(- 80)^{2} - 4 \cdot 1 \cdot (- 900) = 100

x_{1, 2} = \frac{- ( - 80 ) \pm 100}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 80 ) + 100}{2 \cdot 1}, x_{2} = \frac{- ( - 80 ) - 100}{2 \cdot 1}

x = \frac{- ( - 80 ) + 100}{2 \cdot 1} : 90

x = \frac{- ( - 80 ) - 100}{2 \cdot 1} : - 10

The solutions to the quadratic equation are:

x = 90, x = - 10

\frac{- w + 6}{2} < 5

5 \geq \frac{6 - 5 x}{3} > 2

\frac{4}{10} x - 2 x + \frac{6}{5} = \frac{4}{5}
