x^{2} + 22 x = 4

x = - 11 + 55, x = - 11 - 55

Decimal Notation

x = 0.18033 \dots, x = - 22.18033 \dots

Solution steps

x^{2} + 22 x = 4

Move

4

to the left side

x^{2} + 22 x - 4 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 22 \pm 2 2 ^{2} - 4 \cdot 1 \cdot ( - 4 )}{2 \cdot 1}

2 2^{2} - 4 \cdot 1 \cdot (- 4) = 105

x_{1, 2} = \frac{- 22 \pm 10 5}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 22 + 10 5}{2 \cdot 1}, x_{2} = \frac{- 22 - 10 5}{2 \cdot 1}

x = \frac{- 22 + 10 5}{2 \cdot 1} : - 11 + 55

x = \frac{- 22 - 10 5}{2 \cdot 1} : - 11 - 55

The solutions to the quadratic equation are:

x = - 11 + 55, x = - 11 - 55
