I need help with these two problems I also need work I can't quite figure out how to do them thanks, sarah. ^=an exponent. You can also use synthetic division.
4a^3 - 8a^2 + a^2 divided by (4a)-1
& f^2 + 7f +10 divided by f+2

I'm in 10th grade and the first problem IS typed right I double checked :/ it's SOOO confusing..
2007-12-12 11:32:08 · update #2
f^2 + 7f +10 divided by f+2
f^2 + 7f +10/ f+2
(f+5) (f+2) / F+2
Cancel out the (f+2) and the top with the one at the bottom
Answer is F+5

4a^3 - 8a^2 + a^2 divided by (4a)-1:
(8a to the negative 2 b cube c to the negative 4/4a squared b to the negative 3 c squared) to the negative 2
Hi there.
I think your description matches this expression:
When you multiply terms that have the same base, you add their exponents. When you divide such terms, you subtract their exponents. For example, a2 divided by a2 equals a2-2. Use this rule to simplify what is inside the parentheses for all your terms.
When you have a term with an exponent, such as a-4, and you raise that to another exponent, you multiply the exponents. For example, (a-4)-2 equals a(-2)(-4), which is a8. Use this rule to apply the exponent outside the parentheses to the exponents inside the parentheses. Remember to apply it to the numbers inside the parentheses as well as the variables.
Hope this helps

f^2 + 7f +10 divided by f+2
= [(f+ 2)(f+5)] / (f+2)
= f + 5

(4a^3-7a^2)/ (4a-1)= 4a^2(a-7) <= [are you sure you typed the problem out right I cant get anywhere]
&
(f+5)(f+2) /(f+2)= (f+5) <=[the (f+2) cancel each other out]

Are you sure you`ve posted the first on correctly ?
2. (f^2 + 7x + 10)/(f + 2)
= (f + 5)(f + 2)/(f + 2)
= (f + 5)
Hope this helps, Twiggy.

OK i will try but I am only in seventh grade but I am in excelerated math. I think the answer to the first one is... OMG how the heck do I figure this out! What grade are you in anyway?
