2 x^{2} - 9 x - 11 = 0

x = \frac{11}{2}, x = - 1

Decimal Notation

x = 5.5, x = - 1

Solution steps

2 x^{2} - 9 x - 11 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 9 ) \pm ( - 9 ) ^{2} - 4 \cdot 2 ( - 11 )}{2 \cdot 2}

(- 9)^{2} - 4 \cdot 2 (- 11) = 13

x_{1, 2} = \frac{- ( - 9 ) \pm 13}{2 \cdot 2}

Separate the solutions

x_{1} = \frac{- ( - 9 ) + 13}{2 \cdot 2}, x_{2} = \frac{- ( - 9 ) - 13}{2 \cdot 2}

x = \frac{- ( - 9 ) + 13}{2 \cdot 2} : \frac{11}{2}

x = \frac{- ( - 9 ) - 13}{2 \cdot 2} : - 1

The solutions to the quadratic equation are:

x = \frac{11}{2}, x = - 1
