10 n^{2} + 21 n + 9 = 0

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

Decimal Notation

n = - 0.6, n = - 1.5

Solution steps

10 n^{2} + 21 n + 9 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 21 \pm 2 1 ^{2} - 4 \cdot 10 \cdot 9}{2 \cdot 10}

2 1^{2} - 4 \cdot 10 \cdot 9 = 9

n_{1, 2} = \frac{- 21 \pm 9}{2 \cdot 10}

Separate the solutions

n_{1} = \frac{- 21 + 9}{2 \cdot 10}, n_{2} = \frac{- 21 - 9}{2 \cdot 10}

n = \frac{- 21 + 9}{2 \cdot 10} : - \frac{3}{5}

n = \frac{- 21 - 9}{2 \cdot 10} : - \frac{3}{2}

The solutions to the quadratic equation are:

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

1 - x^{2} = - 29

x, x^{2} + y^{2} = z^{2}

4 (x + 6)^{2} - 50 = 26

(x - 8)^{2} + 12 = 41

x^{2} - 24 x + 144 = - 100
