x^{2} + 10 x - 18 = 0

x = - 5 + 43, x = - 5 - 43

Decimal Notation

x = 1.55743 \dots, x = - 11.55743 \dots

Solution steps

x^{2} + 10 x - 18 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 10 \pm 1 0 ^{2} - 4 \cdot 1 \cdot ( - 18 )}{2 \cdot 1}

1 0^{2} - 4 \cdot 1 \cdot (- 18) = 243

x_{1, 2} = \frac{- 10 \pm 2 43}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 10 + 2 43}{2 \cdot 1}, x_{2} = \frac{- 10 - 2 43}{2 \cdot 1}

x = \frac{- 10 + 2 43}{2 \cdot 1} : - 5 + 43

x = \frac{- 10 - 2 43}{2 \cdot 1} : - 5 - 43

The solutions to the quadratic equation are:

x = - 5 + 43, x = - 5 - 43

(3 x - 2)^{2} = (2 x + 1) (2 x - 1) - 2

4 x^{2} + 3 x - 4 = 0

36 x^{2} - 18 x - 180 = 0

p^{2} + 15 p + 56 = 0

x^{2} - 0.5 = 0
