Factorise:<br> 3x3-3x2y+xy2-x2y
qaws [65]

3x^3-3x^2y+xy^2-x^2y

All terms have an x in them, so you factor that out first to get

x(3x^2 -4xy+y^2)

Now the 2nd degree equation will be of the form (3x- ... y)(x- ... y) and by just trying you find that the ... is just 1. So the factorization is:

x(3x - y)(x - y)

A concession stand sells two sizes of popcorn. The small bag holds 20 ounces and costs $4, and the large bag holds 32 ounces and
Studentka2010 [4]
X = large bag of popcorn
y = small bag of popcorn

x + y = 200...x = 200 - y
4x + 6y = 900

4(200 - y) + 6y = 900
800 - 4y + 6y = 900
-4y + 6y = 900 - 800
2y = 100
y = 50 <=== large bags sold

x + y = 200
x + 50 = 200
x = 200 - 50
x = 150 <== small bags
