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

m = 2, m = - \frac{1}{4}

Solution steps

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

Solve with the quadratic formula

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

(- 7)^{2} - 4 \cdot 4 (- 2) = 9

m_{1, 2} = \frac{- ( - 7 ) \pm 9}{2 \cdot 4}

Separate the solutions

m_{1} = \frac{- ( - 7 ) + 9}{2 \cdot 4}, m_{2} = \frac{- ( - 7 ) - 9}{2 \cdot 4}

m = \frac{- ( - 7 ) + 9}{2 \cdot 4} : 2

m = \frac{- ( - 7 ) - 9}{2 \cdot 4} : - \frac{1}{4}

The solutions to the quadratic equation are:

m = 2, m = - \frac{1}{4}

5 \cdot \frac{3}{2}

\frac{x}{∣ x + 4 ∣} < 0

x^{2} < 81

8 - x^{3}

y - \frac{2}{10} = \frac{9}{7}
