8 n^{2} + 16 n + 15 = 9

n = - \frac{1}{2}, n = - \frac{3}{2}

Solution steps

8 n^{2} + 16 n + 15 = 9

Move

9

to the left side

8 n^{2} + 16 n + 6 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 16 \pm 1 6 ^{2} - 4 \cdot 8 \cdot 6}{2 \cdot 8}

1 6^{2} - 4 \cdot 8 \cdot 6 = 8

n_{1, 2} = \frac{- 16 \pm 8}{2 \cdot 8}

Separate the solutions

n_{1} = \frac{- 16 + 8}{2 \cdot 8}, n_{2} = \frac{- 16 - 8}{2 \cdot 8}

n = \frac{- 16 + 8}{2 \cdot 8} : - \frac{1}{2}

n = \frac{- 16 - 8}{2 \cdot 8} : - \frac{3}{2}

The solutions to the quadratic equation are:

n = - \frac{1}{2}, n = - \frac{3}{2}

- x^{2} + 5 x

\frac{8 ( - m ^{0} n ^{2} ) ^{3} ( - n ^{3} ) ^{2}}{m ^{6} n ^{0} ( - 2 m ^{- 2} n ^{4} ) ^{3}}

x^{3} + 4 x^{2} < 4 x + 16

\frac{x}{2} - 3 = 4

\frac{x}{6} = - 4
