simplify (2+sqrt(x))^2

Solution

simplify

(2 + x)^{2}

Solution

4 + 4 x + x

Solution steps

(2 + x)^{2}

Apply Perfect Square Formula:

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

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

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

2^{2} = 4

2 \cdot 2 x = 4 x

(x)^{2} = x

= 4 + 4 x + x
