x^2+4=(x+2)^2

Solution

x^{2} + 4 = (x + 2)^{2}

Solution

x = 0

Solution steps

x^{2} + 4 = (x + 2)^{2}

Expand

(x + 2)^{2} : x^{2} + 4 x + 4

x^{2} + 4 = x^{2} + 4 x + 4

Move

4

to the right side

x^{2} = x^{2} + 4 x

Subtract

x^{2} + 4 x

from both sides

x^{2} - (x^{2} + 4 x) = x^{2} + 4 x - (x^{2} + 4 x)

Simplify

- 4 x = 0

Divide both sides by

- 4

x = 0
