x^2-8x-240=0

Solution

x^{2} - 8 x - 240 = 0

Solution

x = 20, x = - 12

Solution steps

x^{2} - 8 x - 240 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 8 ) \pm ( - 8 ) ^{2} - 4 \cdot 1 \cdot ( - 240 )}{2 \cdot 1}

(- 8)^{2} - 4 \cdot 1 \cdot (- 240) = 32

x_{1, 2} = \frac{- ( - 8 ) \pm 32}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 8 ) + 32}{2 \cdot 1}, x_{2} = \frac{- ( - 8 ) - 32}{2 \cdot 1}

x = \frac{- ( - 8 ) + 32}{2 \cdot 1} : 20

x = \frac{- ( - 8 ) - 32}{2 \cdot 1} : - 12

The solutions to the quadratic equation are:

x = 20, x = - 12
