5 n^{2} - 6 n - 10 = 15

n = \frac{3 + 134}{5}, n = \frac{3 - 134}{5}

Decimal Notation

n = 2.91516 \dots, n = - 1.71516 \dots

Solution steps

5 n^{2} - 6 n - 10 = 15

Move

15

to the left side

5 n^{2} - 6 n - 25 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 5 ( - 25 )}{2 \cdot 5}

(- 6)^{2} - 4 \cdot 5 (- 25) = 2134

n_{1, 2} = \frac{- ( - 6 ) \pm 2 134}{2 \cdot 5}

Separate the solutions

n_{1} = \frac{- ( - 6 ) + 2 134}{2 \cdot 5}, n_{2} = \frac{- ( - 6 ) - 2 134}{2 \cdot 5}

n = \frac{- ( - 6 ) + 2 134}{2 \cdot 5} : \frac{3 + 134}{5}

n = \frac{- ( - 6 ) - 2 134}{2 \cdot 5} : \frac{3 - 134}{5}

The solutions to the quadratic equation are:

n = \frac{3 + 134}{5}, n = \frac{3 - 134}{5}

\frac{8}{3} - \frac{5}{2}
