X^{2} + 2 X - 5 = 0

X = - 1 + 6, X = - 1 - 6

Decimal Notation

X = 1.44948 \dots, X = - 3.44948 \dots

Solution steps

X^{2} + 2 X - 5 = 0

Solve with the quadratic formula

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

2^{2} - 4 \cdot 1 \cdot (- 5) = 26

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

Separate the solutions

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

X = \frac{- 2 + 2 6}{2 \cdot 1} : - 1 + 6

X = \frac{- 2 - 2 6}{2 \cdot 1} : - 1 - 6

The solutions to the quadratic equation are:

X = - 1 + 6, X = - 1 - 6
