simplify (4+sqrt(x))^2

Solution

simplify

(4 + x)^{2}

Solution

16 + 8 x + x

Solution steps

(4 + x)^{2}

Apply Perfect Square Formula:

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

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

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

4^{2} = 16

2 \cdot 4 x = 8 x

(x)^{2} = x

= 16 + 8 x + x
