x^2+4x-140=0

Solution

x^{2} + 4 x - 140 = 0

Solution

x = 10, x = - 14

Solution steps

x^{2} + 4 x - 140 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 1 \cdot ( - 140 )}{2 \cdot 1}

4^{2} - 4 \cdot 1 \cdot (- 140) = 24

x_{1, 2} = \frac{- 4 \pm 24}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 4 + 24}{2 \cdot 1}, x_{2} = \frac{- 4 - 24}{2 \cdot 1}

x = \frac{- 4 + 24}{2 \cdot 1} : 10

x = \frac{- 4 - 24}{2 \cdot 1} : - 14

The solutions to the quadratic equation are:

x = 10, x = - 14
