I recently enrolled in a high school math course needed to take a college course, but I was always dreadful at math, and this is a correspondence course with minimal student assistance.
I am having some difficulties, and would like help with two question
For this question I got
However I think I am wrong. The next question I found even more confusing
for this one I got 1/-4 but again, i think I am very lose
so here is what I am not getting, why do you not just multiply the exponents? IE (a+b)(a-b) = (a2-b2)
and if I do (xa+b) = (xaxb, then where do I go from there with the exponents outside the bracket?
could someone show me what step 2 and three of this question would look like?
