n^{2} + 6 n = 7

n = 1, n = - 7

Solution steps

n^{2} + 6 n = 7

Move

7

to the left side

n^{2} + 6 n - 7 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 6 \pm 6 ^{2} - 4 \cdot 1 \cdot ( - 7 )}{2 \cdot 1}

6^{2} - 4 \cdot 1 \cdot (- 7) = 8

n_{1, 2} = \frac{- 6 \pm 8}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- 6 + 8}{2 \cdot 1}, n_{2} = \frac{- 6 - 8}{2 \cdot 1}

n = \frac{- 6 + 8}{2 \cdot 1} : 1

n = \frac{- 6 - 8}{2 \cdot 1} : - 7

The solutions to the quadratic equation are:

n = 1, n = - 7

y^{2} + 9 y + 18

\frac{5 ^{3}}{2}

(x + 6)^{2} (x - 7) < 0

\frac{8}{20} \cdot \frac{7}{19}
