x^{2} + 22 x + 121 = 15

x = - 11 + 15, x = - 11 - 15

Decimal Notation

x = - 7.12701 \dots, x = - 14.87298 \dots

Solution steps

x^{2} + 22 x + 121 = 15

Move

15

to the left side

x^{2} + 22 x + 106 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 22 \pm 2 2 ^{2} - 4 \cdot 1 \cdot 106}{2 \cdot 1}

2 2^{2} - 4 \cdot 1 \cdot 106 = 215

x_{1, 2} = \frac{- 22 \pm 2 15}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 22 + 2 15}{2 \cdot 1}, x_{2} = \frac{- 22 - 2 15}{2 \cdot 1}

x = \frac{- 22 + 2 15}{2 \cdot 1} : - 11 + 15

x = \frac{- 22 - 2 15}{2 \cdot 1} : - 11 - 15

The solutions to the quadratic equation are:

x = - 11 + 15, x = - 11 - 15

4 a - \frac{a ^{2}}{2} = 1

t^{2} + 9 t + 18

2 x - 1 = x^{2}

3 (2 x + 2) > 24 - 4 x
