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

x = 7, x = - 7

Decimal Notation

x = 2.64575 \dots, x = - 2.64575 \dots

Solution steps

x^{2} + 0 \cdot x + 2 = 9

Refine

x^{2} + 2 = 9

Move

9

to the left side

x^{2} - 7 = 0

Solve with the quadratic formula

x_{1, 2} = \frac{- 0 \pm 0 ^{2} - 4 \cdot 1 \cdot ( - 7 )}{2 \cdot 1}

0^{2} - 4 \cdot 1 \cdot (- 7) = 27

x_{1, 2} = \frac{- 0 \pm 2 7}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 0 + 2 7}{2 \cdot 1}, x_{2} = \frac{- 0 - 2 7}{2 \cdot 1}

x = \frac{- 0 + 2 7}{2 \cdot 1} : 7

x = \frac{- 0 - 2 7}{2 \cdot 1} : - 7

The solutions to the quadratic equation are:

x = 7, x = - 7

x (x + 1) (x + 3) (x + 5) - x (x + 3) (x + 5)

2 - (- 5)

∣ 2 x + 1 ∣ - 1 > 2

x^{2} - 4 x y - 5 y^{2}
