x^{2} + 2 x - 23 = 0

x = - 1 + 26, x = - 1 - 26

Decimal Notation

x = 3.89897 \dots, x = - 5.89897 \dots

Solution steps

x^{2} + 2 x - 23 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 2 \pm 2 ^{2} - 4 \cdot 1 \cdot ( - 23 )}{2 \cdot 1}

2^{2} - 4 \cdot 1 \cdot (- 23) = 46

x_{1, 2} = \frac{- 2 \pm 4 6}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 2 + 4 6}{2 \cdot 1}, x_{2} = \frac{- 2 - 4 6}{2 \cdot 1}

x = \frac{- 2 + 4 6}{2 \cdot 1} : - 1 + 26

x = \frac{- 2 - 4 6}{2 \cdot 1} : - 1 - 26

The solutions to the quadratic equation are:

x = - 1 + 26, x = - 1 - 26

∣ x + 7 ∣ + 5 \leq 7

- 3 - 8 \leq - 23
