9 x^{2} + 30 x + 25 = 11

x = \frac{- 5 + 11}{3}, x = - \frac{5 + 11}{3}

Decimal Notation

x = - 0.56112 \dots, x = - 2.77220 \dots

Solution steps

9 x^{2} + 30 x + 25 = 11

Move

11

to the left side

9 x^{2} + 30 x + 14 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 30 \pm 3 0 ^{2} - 4 \cdot 9 \cdot 14}{2 \cdot 9}

3 0^{2} - 4 \cdot 9 \cdot 14 = 611

x_{1, 2} = \frac{- 30 \pm 6 11}{2 \cdot 9}

Separate the solutions

x_{1} = \frac{- 30 + 6 11}{2 \cdot 9}, x_{2} = \frac{- 30 - 6 11}{2 \cdot 9}

x = \frac{- 30 + 6 11}{2 \cdot 9} : \frac{- 5 + 11}{3}

x = \frac{- 30 - 6 11}{2 \cdot 9} : - \frac{5 + 11}{3}

The solutions to the quadratic equation are:

x = \frac{- 5 + 11}{3}, x = - \frac{5 + 11}{3}

3 \cdot 2 - 2 y = 6

x^{2} - 22 x + 21

- 1 - \frac{8}{3} (\frac{1}{4} x) = 2

\frac{2 x - 1}{4} + \frac{x}{3} = 2
