simplify (sqrt(x)-2)^2

Solution

simplify

(x - 2)^{2}

Solution

x - 4 x + 4

Solution steps

(x - 2)^{2}

Apply Perfect Square Formula:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(x - 2)^{2} = (x)^{2} - 2 x \cdot 2 + 2^{2}

= (x)^{2} - 2 x \cdot 2 + 2^{2}

(x)^{2} = x

- 2 x \cdot 2 = - 4 x

2^{2} = 4

= x - 4 x + 4
