2 n^{2} - 6 n = 8

n = 4, n = - 1

Solution steps

2 n^{2} - 6 n = 8

Move

8

to the left side

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

Solve with the quadratic formula

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

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

n = 4, n = - 1

u^{2} = 11 u

x^{2} - x - 1 > 0

5 u - 9 = - 7 u - 9

\frac{- 21 w ^{5} x ^{2}}{7 w ^{4} x ^{5}}

x^{2} - 9 x + 14 \leq 0
