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

m = 4, m = - 1

Solution steps

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

Solve with the quadratic formula

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

(- 6)^{2} - 4 \cdot 2 (- 8) = 10

m_{1, 2} = \frac{- ( - 6 ) \pm 10}{2 \cdot 2}

Separate the solutions

m_{1} = \frac{- ( - 6 ) + 10}{2 \cdot 2}, m_{2} = \frac{- ( - 6 ) - 10}{2 \cdot 2}

m = \frac{- ( - 6 ) + 10}{2 \cdot 2} : 4

m = \frac{- ( - 6 ) - 10}{2 \cdot 2} : - 1

The solutions to the quadratic equation are:

m = 4, m = - 1

x, \frac{x ^{2}}{q} + \frac{y ^{2}}{4} = 1

x, f = 2 x^{2} - 2 x + 1

2 (x - 2)^{2} - (3 x - 6) = 9

x^{2} + 6 x - 100 = 0

x^{2} + 1.6 x = 0.36
