expand (ln(x)-15)^2

expand

(ln (x) - 15)^{2}

ln^{2} (x) - 30 ln (x) + 225

Solution steps

(ln (x) - 15)^{2}

Apply Perfect Square Formula:

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

a = ln (x), b = 15

= ln^{2} (x) - 2 ln (x) \cdot 15 + 1 5^{2}

Simplify

ln^{2} (x) - 2 ln (x) \cdot 15 + 1 5^{2} : ln^{2} (x) - 30 ln (x) + 225

= ln^{2} (x) - 30 ln (x) + 225

\frac{( 1 + s ) ^{4}}{p ^{2} n ^{2}}

11 + - 36

2 \times 3 - 9

(e^{x} + 1)^{2} e^{x}

\frac{b ^{2} c}{( a - b ) ( a - c ) ( b + c )}
