Question 439409: I need to factor these polynomials out completely.... Can you plz show step by step and explain it??
(C) 108y-4y^4 (D) 63m^3n^2-7mn^4 Found 2 solutions by shantalboodram, robertb:Answer by shantalboodram(15) (Show Source):
You can put this solution on YOUR website! c) 108y-4y^4
The common factors here are 4 and y
therefore take these two terms outside the brackets as seen below:
4y(27 - y^3)
Note:
108y/4y = 27 and 4y^4/4y = y^3
d) 63m^3n^2 - 7mn^4
look for the terms that are common to both numbers
in this case, it is 7mn^2
so:
7mn^2(9m^2 - n^2)
