2 m^{2} - 7 m - 660 = 0

m = 20, m = - \frac{33}{2}

Decimal Notation

m = 20, m = - 16.5

Solution steps

2 m^{2} - 7 m - 660 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 7 ) \pm ( - 7 ) ^{2} - 4 \cdot 2 ( - 660 )}{2 \cdot 2}

(- 7)^{2} - 4 \cdot 2 (- 660) = 73

m_{1, 2} = \frac{- ( - 7 ) \pm 73}{2 \cdot 2}

Separate the solutions

m_{1} = \frac{- ( - 7 ) + 73}{2 \cdot 2}, m_{2} = \frac{- ( - 7 ) - 73}{2 \cdot 2}

m = \frac{- ( - 7 ) + 73}{2 \cdot 2} : 20

m = \frac{- ( - 7 ) - 73}{2 \cdot 2} : - \frac{33}{2}

The solutions to the quadratic equation are:

m = 20, m = - \frac{33}{2}

6 x - 2 \leq 3 x - 6

4 (x + 2) = - 2 (x - 1)

\frac{x}{5} + 6.2 = - 6.3

0.58 = (- 5 \cdot 1 0^{- 7}) x^{2} + 0.0018 x + 0.0593
