5 n^{2} + 5 n - 10 = 0

n = 1, n = - 2

Solution steps

5 n^{2} + 5 n - 10 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 5 \pm 5 ^{2} - 4 \cdot 5 ( - 10 )}{2 \cdot 5}

5^{2} - 4 \cdot 5 (- 10) = 15

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

Separate the solutions

n_{1} = \frac{- 5 + 15}{2 \cdot 5}, n_{2} = \frac{- 5 - 15}{2 \cdot 5}

n = \frac{- 5 + 15}{2 \cdot 5} : 1

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

The solutions to the quadratic equation are:

n = 1, n = - 2

3 x^{2} + 5 x = 12

0 = 2 x^{2} - 8 x - 24

x^{2} + 4 x - 12 = 0

- 13 y - (y - 4) 2 + 8 (2 y - 3) = 8 - (y + 5) (y - 5) - 10 (y + 1)

x^{2} - 37 x + 311 = 0
