I dont understand lol
So it must be more difficult to understand 
-
so basically, you have to write down all factors of the coefficients of p.
Then you write down all coefficients of the constant.
then find a pair of factors which can pair up with each other to give the middle number.
and thats it.

21p(2) + 15p - 6
(__p + ___) (__p + ___)
(21p + ___) (1p + ___)
(Note: 21 - 6 = 15)
So...
(21P - 6)(1p + 1)
Then...
30p(2) - 19p - 4
(__p + ___)(__p + ___)
factors of 30: 30X1, 15X2, 3X10, 5X6
factors of 4: 4X1, 2X2
to get -19, we need 5X6 and 4X1
(Note: 5-24)
So
(5p-4)(6p+1)

Actually I teach you a method

lets say: Like the previous question:
6K(2) + K - 15
You write this down:
6K(2) - 15
.
(__K + __)(__K - ___)
Then you fill in the blanks.
for the ones infront of K, they must multiply to get 6.

Yay! \o/
These are quite simple. The numbers are still small~ XD -
(8-r)(3+r) <------
(9-r)(6+r) <------
But do you know how to get them? Its pretty easy you know... These can be calculated in the brain.
-
so you need to factorise it? Or get the answer?

2(r-8)(r-3) <-----
2(r-5)(r-2) <-----
Need me to explain?

I see XD Need my help?

(Actually not sure whether she can help but she's pretty interested when it comes to math so...
)
