15 n^{2} - 22 n + 8 = 0

n = \frac{4}{5}, n = \frac{2}{3}

Decimal Notation

n = 0.8, n = 0.66666 \dots

Solution steps

15 n^{2} - 22 n + 8 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 22 ) \pm ( - 22 ) ^{2} - 4 \cdot 15 \cdot 8}{2 \cdot 15}

(- 22)^{2} - 4 \cdot 15 \cdot 8 = 2

n_{1, 2} = \frac{- ( - 22 ) \pm 2}{2 \cdot 15}

Separate the solutions

n_{1} = \frac{- ( - 22 ) + 2}{2 \cdot 15}, n_{2} = \frac{- ( - 22 ) - 2}{2 \cdot 15}

n = \frac{- ( - 22 ) + 2}{2 \cdot 15} : \frac{4}{5}

n = \frac{- ( - 22 ) - 2}{2 \cdot 15} : \frac{2}{3}

The solutions to the quadratic equation are:

n = \frac{4}{5}, n = \frac{2}{3}

2 x^{2} + 7 x - 5 = 0

\frac{6 2}{2}

- 3 x^{2} + 2 = 0

6 x^{2} - 30 = 0
