Question

'Factorising' a polynomial means writing it as a product of its factors.

Which of the following is a factorised form of 15w7 + 6w6 - 10w5 - 21w4 - 25w3 + 33w?
A
(15w6 + 6w5 - 10w4 - 21w3 - 25w2 + 33)w
B
5w(3w6 - 2w4 + 5w2) + 3( 2w6 - 7w2 +11w)
C
w(15w7 - 10w5 - 25w2) + w( 6w5 - 21w3 +33)
D
All of the above are factorised forms of 15w7 + 6w6 - 10w5 - 21w4 - 25w2 + 33w.
