expand (ln(x)+2)^2

Solution

expand

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

Solution

ln^{2} (x) + 4 ln (x) + 4

Solution steps

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

Apply Perfect Square Formula:

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

a = ln (x), b = 2

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

Simplify

ln^{2} (x) + 2 ln (x) \cdot 2 + 2^{2} : ln^{2} (x) + 4 ln (x) + 4

= ln^{2} (x) + 4 ln (x) + 4
