x^2+2.2x+1.21=0

Solution

x^{2} + 2.2 x + 1.21 = 0

Solution

x = - \frac{11}{10}

+1

Solution steps

x^{2} + 2.2 x + 1.21 = 0

Multiply both sides by

100

100 x^{2} + 220 x + 121 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 220 \pm 22 0 ^{2} - 4 \cdot 100 \cdot 121}{2 \cdot 100}

22 0^{2} - 4 \cdot 100 \cdot 121 = 0

x_{1, 2} = \frac{- 220 \pm 0}{2 \cdot 100}

x = \frac{- 220}{2 \cdot 100}

\frac{- 220}{2 \cdot 100} = - \frac{11}{10}

x = - \frac{11}{10}

The solution to the quadratic equation is:

x = - \frac{11}{10}
