x^{2} + x \cdot 0 + 0^{2} = 7

x = 7, x = - 7

Decimal Notation

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

Solution steps

x^{2} + x \cdot 0 + 0^{2} = 7

Expand

x^{2} + x \cdot 0 + 0^{2} : x^{2}

x^{2} = 7

Move

7

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

2 x^{2} - 5 x = 88

64 x^{2} + 80 x + 16 = 0

\frac{x}{3} (x + 5) = 0

618 = 232 x + 4.9 x^{2}

11 = \frac{2}{3} (8 x + 12) 32 (8 x + 12)
