20 m^{2} + 7 m - 6 = 0

m = \frac{2}{5}, m = - \frac{3}{4}

Decimal Notation

m = 0.4, m = - 0.75

Solution steps

20 m^{2} + 7 m - 6 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 20 ( - 6 )}{2 \cdot 20}

7^{2} - 4 \cdot 20 (- 6) = 23

m_{1, 2} = \frac{- 7 \pm 23}{2 \cdot 20}

Separate the solutions

m_{1} = \frac{- 7 + 23}{2 \cdot 20}, m_{2} = \frac{- 7 - 23}{2 \cdot 20}

m = \frac{- 7 + 23}{2 \cdot 20} : \frac{2}{5}

m = \frac{- 7 - 23}{2 \cdot 20} : - \frac{3}{4}

The solutions to the quadratic equation are:

m = \frac{2}{5}, m = - \frac{3}{4}

9 x = (0.5 x^{2}) + 40

x, f (x + 4) = x^{2} + 3 x

0 = 4.905 t^{2} + 5 t
