Homework Help: Belinda, Math

Posted by Jasmine20 on Wednesday, January 24, 2007 at 10:40pm.

Thank you I did figure it out i think:

so the problem was

((w)-(1)/(4))^2

The final answer that i got was

w^2-(1)/(2)w+ (1)/(16)

Sorry, no again. :) Make sure you really look at how to multiply binomials and FOIL them out. It will come back to haunt you. a lot.

These are the steps i did:
(w-(1)/(4))^2

so from the problem i did this:

(w-(1)/(4))(w-(1)/(4))
so then i foil out:

=w^2-(1)/(4)w-(1)/(4)w+(1)/(16)
then i combined like terms
to get my answer

w^2-(1)/(2)w+(1)/(16)

You have the answer right, but don't do it like that. Do the numerator and denominator separately to make your life a little easier.
