2 n^{2} + 15 n + 13 = 0

n = - 1, n = - \frac{13}{2}

Decimal Notation

n = - 1, n = - 6.5

Solution steps

2 n^{2} + 15 n + 13 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 2 \cdot 13}{2 \cdot 2}

1 5^{2} - 4 \cdot 2 \cdot 13 = 11

n_{1, 2} = \frac{- 15 \pm 11}{2 \cdot 2}

Separate the solutions

n_{1} = \frac{- 15 + 11}{2 \cdot 2}, n_{2} = \frac{- 15 - 11}{2 \cdot 2}

n = \frac{- 15 + 11}{2 \cdot 2} : - 1

n = \frac{- 15 - 11}{2 \cdot 2} : - \frac{13}{2}

The solutions to the quadratic equation are:

n = - 1, n = - \frac{13}{2}

\frac{7 x}{3} + 2 = - 15

- 7 x \geq - 15

- 6 n < - 12

\frac{2}{8}

- 32 = 4 t
