x^{2} + 14 x - 9 = 0

x = - 7 + 58, x = - 7 - 58

Decimal Notation

x = 0.61577 \dots, x = - 14.61577 \dots

Solution steps

x^{2} + 14 x - 9 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 14 \pm 1 4 ^{2} - 4 \cdot 1 \cdot ( - 9 )}{2 \cdot 1}

1 4^{2} - 4 \cdot 1 \cdot (- 9) = 258

x_{1, 2} = \frac{- 14 \pm 2 58}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 14 + 2 58}{2 \cdot 1}, x_{2} = \frac{- 14 - 2 58}{2 \cdot 1}

x = \frac{- 14 + 2 58}{2 \cdot 1} : - 7 + 58

x = \frac{- 14 - 2 58}{2 \cdot 1} : - 7 - 58

The solutions to the quadratic equation are:

x = - 7 + 58, x = - 7 - 58

x, 5 x^{2} + x y - y^{2} + 5 x = 0

(x - 8) (x - 8) = 0

x^{2} + 2 x - 483 = 0

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

(x - 7)^{2} = 50
