Re: Equations with parenthesis?

If I remember you had 8 / 100 xy. Looks like you divided 100 by 4 to get 25 but did not do that to the 8????

Re: Equations with parenthesis?

Ooooh! Typo!

8/4 = 2

1/100x^2 + 2/25xy + 2/25y^2

Post # 924 answer 1/100x^2 + 4/25xy + 4/25y^2?

Your latest answer 1/100x^2 + 2/25xy + 2/25y^2

Re: Equations with parenthesis?

I still don't get it, did you not say that the original "8" was not divided properly?

Re: Equations with parenthesis?

Yes, you correctly divided through on the second term in your latest answer, why does that change the last term?

Re: Equations with parenthesis?

Well yes, why does working on ( 8 / 100 ) xy affect the ( 4 / 25 ) y^2 ?

Re: Equations with parenthesis?

I have 150 more problems just like that one... If we do 17 per day...

I am going to make a tuna sandwich! I have celery rolls and mayo and 51 cans of tuna fish. Starkist! I will require about 15-20 minutes.

Re: Equations with parenthesis?

Perhaps, but do you recall what you said to me? That you'd give my new problems a look and try to help me with them?

Alright, have fun! If I am not here when you return it is because I am eating dinner. I will post saying so if I leave.

Yes, I will help you with the new problem. Please just wait for me to finish if you can, I was just joking about the 150 problems.

Alright. You were joking? I doubt that.

I will try, but my family wants me to eat with them, otherwise I'd just eat at the computer.

Re: Equations with parenthesis?

Alright, this time we have "Factoring Trinomials", which is basically "un-multiplying" or working backwards right?

Here:

x² - 8x + 16

I wasn't sure how to do these.
