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

x = \frac{- 7 + 57}{2}, x = \frac{- 7 - 57}{2}

Decimal Notation

x = 0.27491 \dots, x = - 7.27491 \dots

Solution steps

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

Solve with the quadratic formula

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

7^{2} - 4 \cdot 1 \cdot (- 2) = 57

x_{1, 2} = \frac{- 7 \pm 57}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 7 + 57}{2 \cdot 1}, x_{2} = \frac{- 7 - 57}{2 \cdot 1}

x = \frac{- 7 + 57}{2 \cdot 1} : \frac{- 7 + 57}{2}

x = \frac{- 7 - 57}{2 \cdot 1} : \frac{- 7 - 57}{2}

The solutions to the quadratic equation are:

x = \frac{- 7 + 57}{2}, x = \frac{- 7 - 57}{2}

3 x^{2} + 8 x - 11 = 0

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

x^{2} - 11 x + 39 = 9

x^{2} + \frac{11 x}{3} = \frac{5}{12}

6 x^{2} + 96 x - 264 = 0
