x^2+70x-800=0

Solution

x^{2} + 70 x - 800 = 0

Solution

x = 10, x = - 80

Solution steps

x^{2} + 70 x - 800 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 70 \pm 7 0 ^{2} - 4 \cdot 1 \cdot ( - 800 )}{2 \cdot 1}

7 0^{2} - 4 \cdot 1 \cdot (- 800) = 90

x_{1, 2} = \frac{- 70 \pm 90}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 70 + 90}{2 \cdot 1}, x_{2} = \frac{- 70 - 90}{2 \cdot 1}

x = \frac{- 70 + 90}{2 \cdot 1} : 10

x = \frac{- 70 - 90}{2 \cdot 1} : - 80

The solutions to the quadratic equation are:

x = 10, x = - 80
