Question

How do you solve this equation: title="\frac{(2-b)^2}{(b-2)^2}" alt="\frac{(2-b)^2}{(b-2)^2}" align="absmiddle" class="latex-formula">

Answer 1

Answer:

1

Step-by-step explanation:

For the top, you can write it as (2-b)^2 = (-1(b-2))^2 = (-1)^2(b-2)^2 = 1(b-2)^2 = (b-2)^2. Putting that back in, we get: ((b-2)^2)/((b-2)^2) = 1 because the top and bottom cancel.

I hope this helps! :)
