2 x^{2} - 7 x - 2 = 0

x = \frac{7 + 65}{4}, x = \frac{7 - 65}{4}

Solution steps

2 x^{2} - 7 x - 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 2 ( - 2 )}{2 \cdot 2}

(- 7)^{2} - 4 \cdot 2 (- 2) = 65

x_{1, 2} = \frac{- ( - 7 ) \pm 65}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 7 ) + 65}{2 \cdot 2}, x_{2} = \frac{- ( - 7 ) - 65}{2 \cdot 2}

x = \frac{- ( - 7 ) + 65}{2 \cdot 2} : \frac{7 + 65}{4}

x = \frac{- ( - 7 ) - 65}{2 \cdot 2} : \frac{7 - 65}{4}

The solutions to the quadratic equation are:

x = \frac{7 + 65}{4}, x = \frac{7 - 65}{4}
