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
