8 m^{2} - 6 m - 9 = 0

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

Decimal Notation

m = 1.5, m = - 0.75

Solution steps

8 m^{2} - 6 m - 9 = 0

Solve with the quadratic formula

m_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 8 ( - 9 )}{2 \cdot 8}

(- 6)^{2} - 4 \cdot 8 (- 9) = 18

m_{1, 2} = \frac{- ( - 6 ) \pm 18}{2 \cdot 8}

Separate the solutions

m_{1} = \frac{- ( - 6 ) + 18}{2 \cdot 8}, m_{2} = \frac{- ( - 6 ) - 18}{2 \cdot 8}

m = \frac{- ( - 6 ) + 18}{2 \cdot 8} : \frac{3}{2}

m = \frac{- ( - 6 ) - 18}{2 \cdot 8} : - \frac{3}{4}

The solutions to the quadratic equation are:

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

\frac{2 π}{π}

x^{8} - 17 x^{4} + 16

(4 + 5 i) (4 - 5 i)

- \frac{π}{4} + \frac{π}{2}

x^{2} + 16 x + 55 = 0
