7 x^{2} - 3 x - 972 = 0

x = 12, x = - \frac{81}{7}

Decimal Notation

x = 12, x = - 11.57142 \dots

Solution steps

7 x^{2} - 3 x - 972 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 7 ( - 972 )}{2 \cdot 7}

(- 3)^{2} - 4 \cdot 7 (- 972) = 165

x_{1, 2} = \frac{- ( - 3 ) \pm 165}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 3 ) + 165}{2 \cdot 7}, x_{2} = \frac{- ( - 3 ) - 165}{2 \cdot 7}

x = \frac{- ( - 3 ) + 165}{2 \cdot 7} : 12

x = \frac{- ( - 3 ) - 165}{2 \cdot 7} : - \frac{81}{7}

The solutions to the quadratic equation are:

x = 12, x = - \frac{81}{7}

3 x^{2} - 30 x - 11 = 6 x

\frac{1}{7} \cdot 5

- 3 x + 20 > 2 x + 5
