11 x^{2} + 7 x - 30 = 0

x = \frac{15}{11}, x = - 2

Decimal Notation

x = 1.36363 \dots, x = - 2

Solution steps

11 x^{2} + 7 x - 30 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 7 \pm 7 ^{2} - 4 \cdot 11 ( - 30 )}{2 \cdot 11}

7^{2} - 4 \cdot 11 (- 30) = 37

x_{1, 2} = \frac{- 7 \pm 37}{2 \cdot 11}

Separate the solutions

x_{1} = \frac{- 7 + 37}{2 \cdot 11}, x_{2} = \frac{- 7 - 37}{2 \cdot 11}

x = \frac{- 7 + 37}{2 \cdot 11} : \frac{15}{11}

x = \frac{- 7 - 37}{2 \cdot 11} : - 2

The solutions to the quadratic equation are:

x = \frac{15}{11}, x = - 2

x^{2} + 6 x + 5 = 0

8 x^{2} = - 2 + 17 x

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

6 x^{2} - 19 x - 7 = 0

- 2 x^{2} + 4 x + 16 = 0
