n^{2} + 8 n + 15 = 0

n = - 3, n = - 5

Solution steps

n^{2} + 8 n + 15 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 8 \pm 8 ^{2} - 4 \cdot 1 \cdot 15}{2 \cdot 1}

8^{2} - 4 \cdot 1 \cdot 15 = 2

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

Separate the solutions

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

n = \frac{- 8 + 2}{2 \cdot 1} : - 3

n = \frac{- 8 - 2}{2 \cdot 1} : - 5

The solutions to the quadratic equation are:

n = - 3, n = - 5

\frac{x + 3}{4} < \frac{2 x - 4}{3}

lo g_{2} (- 3)

(\frac{1}{40}) (\frac{2 π}{1}) (60)

x^{2} + 8 x - 240 = 0
