expand (sqrt(x)+sqrt(2))^2

expand

(x + 2)^{2}

x + 22 x + 2

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 2 + (2)^{2}

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

Simplify

(x)^{2} + 2 x 2 + (2)^{2} : x + 22 x + 2

= x + 22 x + 2

- \frac{4 x}{( x ^{2} - 1 ) ^{2}}

(x + 1) (x - x + 1)

(e^{i x} + e^{- i x})^{2}

(- 23 - 2 i)^{5}

(x - x^{2}) (sin (x) + x^{2} - 15)
