x^2-13x-68=0

Solution

x^{2} - 13 x - 68 = 0

Solution

x = 17, x = - 4

Solution steps

x^{2} - 13 x - 68 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 13 ) \pm ( - 13 ) ^{2} - 4 \cdot 1 \cdot ( - 68 )}{2 \cdot 1}

(- 13)^{2} - 4 \cdot 1 \cdot (- 68) = 21

x_{1, 2} = \frac{- ( - 13 ) \pm 21}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- ( - 13 ) + 21}{2 \cdot 1}, x_{2} = \frac{- ( - 13 ) - 21}{2 \cdot 1}

x = \frac{- ( - 13 ) + 21}{2 \cdot 1} : 17

x = \frac{- ( - 13 ) - 21}{2 \cdot 1} : - 4

The solutions to the quadratic equation are:

x = 17, x = - 4
