10 x^{2} - 21 x = - 2

x = 2, x = \frac{1}{10}

Decimal Notation

x = 2, x = 0.1

Solution steps

10 x^{2} - 21 x = - 2

Move

2

to the left side

10 x^{2} - 21 x + 2 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 21 ) \pm ( - 21 ) ^{2} - 4 \cdot 10 \cdot 2}{2 \cdot 10}

(- 21)^{2} - 4 \cdot 10 \cdot 2 = 19

x_{1, 2} = \frac{- ( - 21 ) \pm 19}{2 \cdot 10}

Separate the solutions

x_{1} = \frac{- ( - 21 ) + 19}{2 \cdot 10}, x_{2} = \frac{- ( - 21 ) - 19}{2 \cdot 10}

x = \frac{- ( - 21 ) + 19}{2 \cdot 10} : 2

x = \frac{- ( - 21 ) - 19}{2 \cdot 10} : \frac{1}{10}

The solutions to the quadratic equation are:

x = 2, x = \frac{1}{10}

18 - 4 v = 42

\frac{3 - 4 i}{8 + 2 i}

64 a^{3} + 125 b^{3}

\frac{2 ( X - 1 )}{6} + \frac{3 ( X - 2 )}{6} = 2

- x^{2} + 4 x = 6
