x^{2} = 4

x = 2, x = - 2

Solution steps

x^{2} = 4

Move

4

to the left side

x^{2} - 4 = 0

Solve with the quadratic formula

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

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

x_{1, 2} = \frac{- 0 \pm 4}{2 \cdot 1}

Separate the solutions

x_{1} = \frac{- 0 + 4}{2 \cdot 1}, x_{2} = \frac{- 0 - 4}{2 \cdot 1}

x = \frac{- 0 + 4}{2 \cdot 1} : 2

x = \frac{- 0 - 4}{2 \cdot 1} : - 2

The solutions to the quadratic equation are:

x = 2, x = - 2
