21 x^{2} - 6 x = 0

x = \frac{2}{7}, x = 0

Decimal

x = 0.28571 \dots, x = 0

Solution steps

21 x^{2} - 6 x = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 6 ) \pm ( - 6 ) ^{2} - 4 \cdot 21 \cdot 0}{2 \cdot 21}

(- 6)^{2} - 4 \cdot 21 \cdot 0 = 6

x_{1, 2} = \frac{- ( - 6 ) \pm 6}{2 \cdot 21}

Separate the solutions

x_{1} = \frac{- ( - 6 ) + 6}{2 \cdot 21}, x_{2} = \frac{- ( - 6 ) - 6}{2 \cdot 21}

x = \frac{- ( - 6 ) + 6}{2 \cdot 21} : \frac{2}{7}

x = \frac{- ( - 6 ) - 6}{2 \cdot 21} : 0

The solutions to the quadratic equation are:

x = \frac{2}{7}, x = 0

7 - 9 x > 4 - 11 x

x^{2} + (- \frac{5}{7})^{2} = 1^{2}

0.4 \cdot 0.5

(ln (e))^{2}

(x + \frac{5}{2})^{2} - 3 = 18
