x^{2} + 8 x - 65 = 0

x = 5, x = - 13

Solution steps

x^{2} + 8 x - 65 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot ( - 65 )}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot (- 65) = 18

x_{1, 2} = \frac{- 8 \pm 18}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 8 + 18}{2 \cdot 1}, x_{2} = \frac{- 8 - 18}{2 \cdot 1}

x = \frac{- 8 + 18}{2 \cdot 1} : 5

x = \frac{- 8 - 18}{2 \cdot 1} : - 13

The solutions to the quadratic equation are:

x = 5, x = - 13

- 3 n (2 n - 5) = 0

X^{2} + 3 X - 4 = 0
