need help in math:( factorising.. please help!?
what is the answer to this..
8p*little2*q + 12p

I'm going to assume by "little2" you mean squared, which you would show like this: x^2 (Little2 is kinda cute though).
8(p^2)q + 12p Find the greatest common factor
4p(2pq + 3)
20(w^2)*y+ 24w(y^3) Find the greatest common factor
4wy(5w + 6y^2)
If you're having trouble finding the GCF (greatest common factor), don't worry, it's something you get faster at once you have done it a bunch.
If you can't do it mentally you can also break everything up into into prime numbers to find the GCF.
An example of this:
2*2*5*w*w*y + 2*2*2*3*w*y*y*y
It's now easy to see that "2*2*w*y" is the GFC.
(2*2*w*y)(5*w + 2*3*y*y)
4wy(5w + 6y^2)

Lol @ "little 2"; pronounce it "squared" - it means "p multiplied by p" :)
8p²q + 12p
We need to find what is "common" in both parts of this. There is a p in both parts, as well as a multiple of 4. So, we take these outside of our brackets.
4p (2pq + 3). If we expanded this now, we would get 8ppq + 12p, which would be 8p²q + 12p
So, number 2,
The "little 3" is pronounced "cubed", and simply means "p times p times p again".
So, we have a multiple of 4 in both parts again, as well as a w and a y
So, take these outside the bracket:
4wy(5w + 6y²). Again, if this were expanded, we'd get the original back. ^_^.

8p^2q + 12p = 4p(2pq + 3)
20w^2y + 24wy^3 = 4wy(5w + 6y^2)
- TychaBraheLv 79 years ago
8p^2 q + 12 p
4p * (2pq + 3)
20w^2 y + 24wy^3
4wy * (5w + 6y^2)

8p²q + 12p?
20w²y + 24wy³?
