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

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

Solution steps

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}

- 5 x^{2} - 8 x = 15

5^{2} - 20

\frac{2 ^{2 x} - 2 ^{x}}{2 ^{x} - 1}

- 1 = \frac{- b}{1}
