30 x^{2} + 21 x + 3 = 0

x = - \frac{1}{5}, x = - \frac{1}{2}

Decimal Notation

x = - 0.2, x = - 0.5

Solution steps

30 x^{2} + 21 x + 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 21 \pm 2 1 ^{2} - 4 \cdot 30 \cdot 3}{2 \cdot 30}

2 1^{2} - 4 \cdot 30 \cdot 3 = 9

x_{1, 2} = \frac{- 21 \pm 9}{2 \cdot 30}

Separate the solutions

x_{1} = \frac{- 21 + 9}{2 \cdot 30}, x_{2} = \frac{- 21 - 9}{2 \cdot 30}

x = \frac{- 21 + 9}{2 \cdot 30} : - \frac{1}{5}

x = \frac{- 21 - 9}{2 \cdot 30} : - \frac{1}{2}

The solutions to the quadratic equation are:

x = - \frac{1}{5}, x = - \frac{1}{2}

2 x + 32 \leq 42

\frac{x}{5} = 2 + \frac{x + 2}{2}

2 x^{2} + 17 x + 21 \leq 0

\frac{1}{2} + \frac{1}{3} + 1 \leq 2 \cdot 1

\frac{7 \cdot 1 0 ^{9}}{4 \cdot 1 0 ^{2}}
