expand (ln(y)-1)^2

Solution

expand

(ln (y) - 1)^{2}

Solution

ln^{2} (y) - 2 ln (y) + 1

Solution steps

(ln (y) - 1)^{2}

Apply Perfect Square Formula:

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

a = ln (y), b = 1

= ln^{2} (y) - 2 ln (y) \cdot 1 + 1^{2}

Simplify

ln^{2} (y) - 2 ln (y) \cdot 1 + 1^{2} : ln^{2} (y) - 2 ln (y) + 1

= ln^{2} (y) - 2 ln (y) + 1
