7 x^{2} - 34 x - 5 = 0

x = 5, x = - \frac{1}{7}

Decimal Notation

x = 5, x = - 0.14285 \dots

Solution steps

7 x^{2} - 34 x - 5 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 34 ) \pm ( - 34 ) ^{2} - 4 \cdot 7 ( - 5 )}{2 \cdot 7}

(- 34)^{2} - 4 \cdot 7 (- 5) = 36

x_{1, 2} = \frac{- ( - 34 ) \pm 36}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 34 ) + 36}{2 \cdot 7}, x_{2} = \frac{- ( - 34 ) - 36}{2 \cdot 7}

x = \frac{- ( - 34 ) + 36}{2 \cdot 7} : 5

x = \frac{- ( - 34 ) - 36}{2 \cdot 7} : - \frac{1}{7}

The solutions to the quadratic equation are:

x = 5, x = - \frac{1}{7}

x^{2} - 12 x + 12 = 0

42 - 35 + 42 + 85

7 - (3.1 - 0.1 y) = 3 - 0.2 y

9 x^{2} - 16 y^{2}

- 5 - 4 x = 3 - 2 x - x^{2}
