Question

Find the lim a to b idk hiw to do it

Answer 1

$\bf \lim\limits_{a\to b} \cfrac{a^2-3ab+2b^2}{a-b}\implies \lim\limits_{a\to b} \cfrac{(a-1b)(a-2b)}{a-b} \\\\\\ \lim\limits_{a\to b} \cfrac{\underline{(a-b)}(a-2b)}{\underline{a-b}} \implies \lim\limits_{a\to b} a-2b\implies \lim\limits_{a\to b} b-2b\implies \lim\limits_{a\to b}-b$
