7 x^{2} - x - 3 = 0

x = \frac{1 + 85}{14}, x = \frac{1 - 85}{14}

Decimal Notation

x = 0.72996 \dots, x = - 0.58711 \dots

Solution steps

7 x^{2} - x - 3 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- ( - 1 ) \pm ( - 1 ) ^{2} - 4 \cdot 7 ( - 3 )}{2 \cdot 7}

(- 1)^{2} - 4 \cdot 7 (- 3) = 85

x_{1, 2} = \frac{- ( - 1 ) \pm 85}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- ( - 1 ) + 85}{2 \cdot 7}, x_{2} = \frac{- ( - 1 ) - 85}{2 \cdot 7}

x = \frac{- ( - 1 ) + 85}{2 \cdot 7} : \frac{1 + 85}{14}

x = \frac{- ( - 1 ) - 85}{2 \cdot 7} : \frac{1 - 85}{14}

The solutions to the quadratic equation are:

x = \frac{1 + 85}{14}, x = \frac{1 - 85}{14}

10 x^{2} - 11 x + 3

\frac{5}{5}

4 y^{2} - 25 y + 21

2 (x + 55) (x - 17) = 0

- 4 + 9
