n^{2} + 15 n = - 43

n = \frac{- 15 + 53}{2}, n = \frac{- 15 - 53}{2}

Decimal Notation

n = - 3.85994 \dots, n = - 11.14005 \dots

Solution steps

n^{2} + 15 n = - 43

Move

43

to the left side

n^{2} + 15 n + 43 = 0

Solve with the quadratic formula

n_{1, 2} = \frac{- 15 \pm 1 5 ^{2} - 4 \cdot 1 \cdot 43}{2 \cdot 1}

1 5^{2} - 4 \cdot 1 \cdot 43 = 53

n_{1, 2} = \frac{- 15 \pm 53}{2 \cdot 1}

Separate the solutions

n_{1} = \frac{- 15 + 53}{2 \cdot 1}, n_{2} = \frac{- 15 - 53}{2 \cdot 1}

n = \frac{- 15 + 53}{2 \cdot 1} : \frac{- 15 + 53}{2}

n = \frac{- 15 - 53}{2 \cdot 1} : \frac{- 15 - 53}{2}

The solutions to the quadratic equation are:

n = \frac{- 15 + 53}{2}, n = \frac{- 15 - 53}{2}

7 x + x^{2} - 18 = 0

3 x^{2} + 2 x - 5 = 2 x^{2} - 2

(2 x - 3) (x + c) = a x^{2} + b x - 12

3 x^{2} + x - 2 = 0

x^{2} = 7 x + 6
