2 X^{2} + 4 X - 6 = 0

X = 1, X = - 3

Solution steps

2 X^{2} + 4 X - 6 = 0

Solve with the quadratic formula

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

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

X_{1, 2} = \frac{- 4 \pm 8}{2 \cdot 2}

Separate the solutions

X_{1} = \frac{- 4 + 8}{2 \cdot 2}, X_{2} = \frac{- 4 - 8}{2 \cdot 2}

X = \frac{- 4 + 8}{2 \cdot 2} : 1

X = \frac{- 4 - 8}{2 \cdot 2} : - 3

The solutions to the quadratic equation are:

X = 1, X = - 3

\frac{3 x - 2}{5} \geq \frac{2 x - 4}{6}

1 + \frac{2 x}{5} = \frac{1}{5} - 2 x

\frac{3}{4} \cdot 5

\frac{4}{5 a} \cdot \frac{3}{2 a ^{2}}

\frac{- 3 x ^{7} y ^{5}}{x ^{12} y ^{2}}
