x^2+12x-64=0

Solution

x^{2} + 12 x - 64 = 0

Solution

x = 4, x = - 16

Solution steps

x^{2} + 12 x - 64 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 12 \pm 1 2 ^{2} - 4 \cdot 1 \cdot ( - 64 )}{2 \cdot 1}

1 2^{2} - 4 \cdot 1 \cdot (- 64) = 20

x_{1, 2} = \frac{- 12 \pm 20}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 12 + 20}{2 \cdot 1}, x_{2} = \frac{- 12 - 20}{2 \cdot 1}

x = \frac{- 12 + 20}{2 \cdot 1} : 4

x = \frac{- 12 - 20}{2 \cdot 1} : - 16

The solutions to the quadratic equation are:

x = 4, x = - 16
