x^{2} + 3 x - 72 = 0

x = \frac{- 3 + 3 33}{2}, x = \frac{- 3 - 3 33}{2}

Decimal Notation

x = 7.11684 \dots, x = - 10.11684 \dots

Solution steps

x^{2} + 3 x - 72 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 3 \pm 3 ^{2} - 4 \cdot 1 \cdot ( - 72 )}{2 \cdot 1}

3^{2} - 4 \cdot 1 \cdot (- 72) = 333

x_{1, 2} = \frac{- 3 \pm 3 33}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 3 + 3 33}{2 \cdot 1}, x_{2} = \frac{- 3 - 3 33}{2 \cdot 1}

x = \frac{- 3 + 3 33}{2 \cdot 1} : \frac{- 3 + 3 33}{2}

x = \frac{- 3 - 3 33}{2 \cdot 1} : \frac{- 3 - 3 33}{2}

The solutions to the quadratic equation are:

x = \frac{- 3 + 3 33}{2}, x = \frac{- 3 - 3 33}{2}

6 x^{2} - 26 x - 20

3 x - 4 = - 6

2 n + 5 = 20

36 \cdot 8

\frac{n ^{2} + 6 n + 5}{n + 1}
