25 m^{2} - 15 m - 4 = 0

m = \frac{4}{5}, m = - \frac{1}{5}

Decimal Notation

m = 0.8, m = - 0.2

Solution steps

25 m^{2} - 15 m - 4 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 15 ) \pm ( - 15 ) ^{2} - 4 \cdot 25 ( - 4 )}{2 \cdot 25}

(- 15)^{2} - 4 \cdot 25 (- 4) = 25

m_{1, 2} = \frac{- ( - 15 ) \pm 25}{2 \cdot 25}

Separate the solutions

m_{1} = \frac{- ( - 15 ) + 25}{2 \cdot 25}, m_{2} = \frac{- ( - 15 ) - 25}{2 \cdot 25}

m = \frac{- ( - 15 ) + 25}{2 \cdot 25} : \frac{4}{5}

m = \frac{- ( - 15 ) - 25}{2 \cdot 25} : - \frac{1}{5}

The solutions to the quadratic equation are:

m = \frac{4}{5}, m = - \frac{1}{5}

- \frac{4 x}{7} - \frac{2}{6} = 9 x + \frac{3}{7}

9 - \frac{27}{2}

(x) (x + 1) = 1.5 x^{2}

7 x^{2} - 5 x = 0

(x - 5)^{2} = 16
