15 n^{2} + 6 n - 8 = 4 n

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

Decimal Notation

n = 0.66666 \dots, n = - 0.8

Solution steps

15 n^{2} + 6 n - 8 = 4 n

Move

4 n

to the left side

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

Solve with the quadratic formula

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

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

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

Separate the solutions

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

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

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

The solutions to the quadratic equation are:

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

y, 4 y^{2} - 12 x y + 10 x^{2} + 2 x + 1 = 0

z^{2} + 10 z - 24 = 0

4 (9 + 5 x^{2}) = 356

3 v^{2} - 75 = 0

26 n^{2} + 41 n + 20 = 6 n^{2}
