n^{2} + 19 n + 66 = 6

n = - 4, n = - 15

Solution steps

n^{2} + 19 n + 66 = 6

Move

6

to the left side

n^{2} + 19 n + 60 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 19 \pm 1 9 ^{2} - 4 \cdot 1 \cdot 60}{2 \cdot 1}

1 9^{2} - 4 \cdot 1 \cdot 60 = 11

n_{1, 2} = \frac{- 19 \pm 11}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- 19 + 11}{2 \cdot 1}, n_{2} = \frac{- 19 - 11}{2 \cdot 1}

n = \frac{- 19 + 11}{2 \cdot 1} : - 4

n = \frac{- 19 - 11}{2 \cdot 1} : - 15

The solutions to the quadratic equation are:

n = - 4, n = - 15

w, m w^{2} = \frac{9 k \pm 41 k}{4}

0.9 \cdot 0.85 \cdot 210 \cdot 10 \cdot x \cdot (17 - 0.5 \cdot x) = 0.88 \cdot 1 0^{5}

\frac{1}{2} x^{2} - 11 = 25

(x + 1) (x - 4) = 14

- 3 x^{2} + 3 x + 6 = 0
