27 x^{2} + 21 x = 0

x = 0, x = - \frac{7}{9}

Decimal Notation

x = 0, x = - 0.77777 \dots

Solution steps

27 x^{2} + 21 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 21 \pm 2 1 ^{2} - 4 \cdot 27 \cdot 0}{2 \cdot 27}

2 1^{2} - 4 \cdot 27 \cdot 0 = 21

x_{1, 2} = \frac{- 21 \pm 21}{2 \cdot 27}

Separate the solutions

x_{1} = \frac{- 21 + 21}{2 \cdot 27}, x_{2} = \frac{- 21 - 21}{2 \cdot 27}

x = \frac{- 21 + 21}{2 \cdot 27} : 0

x = \frac{- 21 - 21}{2 \cdot 27} : - \frac{7}{9}

The solutions to the quadratic equation are:

x = 0, x = - \frac{7}{9}

x^{4} + 3 x^{3} - 2 x - 6

(x^{2} y^{- 1})^{2}

\frac{3}{4} - \frac{x + 1}{12} = \frac{2}{3} - \frac{x - 1}{6}

- 10 x = - 210
