Question

This is just a check! Please please please help! Will reward medal/ fan you!!!

Factor the polynomial.
72p^2 -50

Answer 1

What are you checking? I don't see your answer here...

Answer 2

Oh... okay.
My answer is 2(6p+5) (6p-5).
Please check if it is right.

Answer 3

It is. Good job!

Here's how I would check, if I didn't already know the answer:

\[2(6p+5)(6p-5) = 2(6p*6p-5*6p+5*6p-5*5) = 2(36p^2-25) = 72p^2-50\checkmark\]

Answer 4

Yes

You could check by expanding it out again.

Answer 5

So, I am right?

Answer 6

what part of "it is" didn't you understand? :-)

Answer 7

Thanks! <3

Answer 11

or a really imaginative wrong answer :-) But yes, beating this horse into ground, you nailed it!

Answer 12

What does beating this horse into ground mean?
Just wondering...and I do have to learn something new everyday, right? ;)

Answer 13

Nice to encounter someone who doesn't need factoring taught to them :-)

have you heard the expression "beating this horse to death"?

Answer 14

No.

Answer 15

or beating a dead horse?

Answer 16

What does it mean?

Answer 17

I think I have heard of beating a dead horse.

Answer 18

I may have....possibly...*

Answer 19

well, it suggests that you've continued past the point of any need to discuss the matter, and yet are still discussing it. We've beaten this dead horse so much, we pounded it into the ground :-)

Answer 20

I see. Thanks for the explanation!
Can you please help me with another similar problem?

Answer 21

Sure, why not, though I already gave you a medal for this one, so if you want another, you'll have to post it in a separate question :-)

Answer 22

Oh, okay! <3
