2x^2-14x-36=0

Solution

2 x^{2} - 14 x - 36 = 0

Solution

x = 9, x = - 2

Solution steps

2 x^{2} - 14 x - 36 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 14 ) \pm ( - 14 ) ^{2} - 4 \cdot 2 ( - 36 )}{2 \cdot 2}

(- 14)^{2} - 4 \cdot 2 (- 36) = 22

x_{1, 2} = \frac{- ( - 14 ) \pm 22}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 14 ) + 22}{2 \cdot 2}, x_{2} = \frac{- ( - 14 ) - 22}{2 \cdot 2}

x = \frac{- ( - 14 ) + 22}{2 \cdot 2} : 9

x = \frac{- ( - 14 ) - 22}{2 \cdot 2} : - 2

The solutions to the quadratic equation are:

x = 9, x = - 2
