5 n^{2} - 3 n - 15 = 0

n = \frac{3 + 309}{10}, n = \frac{3 - 309}{10}

Solution steps

5 n^{2} - 3 n - 15 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- ( - 3 ) \pm ( - 3 ) ^{2} - 4 \cdot 5 ( - 15 )}{2 \cdot 5}

(- 3)^{2} - 4 \cdot 5 (- 15) = 309

n_{1, 2} = \frac{- ( - 3 ) \pm 309}{2 \cdot 5}

Separate the solutions

n_{1} = \frac{- ( - 3 ) + 309}{2 \cdot 5}, n_{2} = \frac{- ( - 3 ) - 309}{2 \cdot 5}

n = \frac{- ( - 3 ) + 309}{2 \cdot 5} : \frac{3 + 309}{10}

n = \frac{- ( - 3 ) - 309}{2 \cdot 5} : \frac{3 - 309}{10}

The solutions to the quadratic equation are:

n = \frac{3 + 309}{10}, n = \frac{3 - 309}{10}
