Proper subset of a set is a subset of that is not equal to. all elements of are in but contains at least one element that is not it
example : if A = { 1,3,5} then B = {1,5} is a proper subset ofz
Answer:
3xy^4+y-2/x
Step-by-step explanation:
12x^3y^4 + 4x^2y -8x
-----------------------------------
4x^2
We can break this fraction into pieces
12x^3y^4 4x^2y 8x
-------------- + --------- - ------------
4x^2 4x^2 4x^2
Taking the first piece
12/4 =3
x^3/x^2 =x
y^4/1 =y^4
3xy^4
Taking the second fractions
4/4=1
x^2/x^2 =1
y=y
y
Taking the third fraction
8/4=2
x/x^2 = 1/x
2/x
Adding them back together
3xy^4+y-2/x
