x, 7 x^{2} + 3 x = 3

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

Move

3

to the left side

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}

6 x^{2} - 13 x + 7 = 0

(x + 5)^{2} = 169

(x + 5)^{2} = 144

(x + 5)^{2} = 100

3 x^{2} - 1 = 11 x
