8 n = n^{2} + 15

n = 5, n = 3

Solution steps

8 n = n^{2} + 15

Switch sides

n^{2} + 15 = 8 n

Move

8 n

to the left side

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

Write in the standard form

a x^{2} + b x + c = 0

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

Solve with the quadratic formula

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

(- 8)^{2} - 4 \cdot 1 \cdot 15 = 2

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

Separate the solutions

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

n = \frac{- ( - 8 ) + 2}{2 \cdot 1} : 5

n = \frac{- ( - 8 ) - 2}{2 \cdot 1} : 3

The solutions to the quadratic equation are:

n = 5, n = 3

(3 x y^{5})^{5}

\frac{2}{7} (x - 3) - \frac{2}{3} = \frac{1}{3} (2 x - 6)

8 (4 u - 1) - 12 u = 11 (2 u - 6)

15 y + 32 = 2 (10 y - 7) - 5 y + 46

3 x - 27 x^{3}
