n^{2} + 4 n - 31 = 0

n = - 2 + 35, n = - 2 - 35

Decimal Notation

n = 3.91607 \dots, n = - 7.91607 \dots

Solution steps

n^{2} + 4 n - 31 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 1 \cdot ( - 31 )}{2 \cdot 1}

4^{2} - 4 \cdot 1 \cdot (- 31) = 235

n_{1, 2} = \frac{- 4 \pm 2 35}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- 4 + 2 35}{2 \cdot 1}, n_{2} = \frac{- 4 - 2 35}{2 \cdot 1}

n = \frac{- 4 + 2 35}{2 \cdot 1} : - 2 + 35

n = \frac{- 4 - 2 35}{2 \cdot 1} : - 2 - 35

The solutions to the quadratic equation are:

n = - 2 + 35, n = - 2 - 35
