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

x = \frac{- 3 + 93}{14}, x = \frac{- 3 - 93}{14}

Decimal Notation

x = 0.47454 \dots, x = - 0.90311 \dots

Solution steps

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

Solve with the quadratic formula

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

3^{2} - 4 \cdot 7 (- 3) = 93

x_{1, 2} = \frac{- 3 \pm 93}{2 \cdot 7}

Separate the solutions

x_{1} = \frac{- 3 + 93}{2 \cdot 7}, x_{2} = \frac{- 3 - 93}{2 \cdot 7}

x = \frac{- 3 + 93}{2 \cdot 7} : \frac{- 3 + 93}{14}

x = \frac{- 3 - 93}{2 \cdot 7} : \frac{- 3 - 93}{14}

The solutions to the quadratic equation are:

x = \frac{- 3 + 93}{14}, x = \frac{- 3 - 93}{14}

2 x^{2} - 4 x - 2 = 0

5 x^{2} + 24 x = - 16

x, x^{2} - 6 x y + y^{2} = 6

a, an = 2 n^{2} - n

y, y^{2} = x (x - 4)^{2}
