1. What are the factors of the following trinomial?

16y^2 - 12y + 2

a) (4y - 1) (4y - 2)
b) (2y - 1) (8y + 2)
c) (16y - 1) (y - 2)
d) (8y - 1) (2y - 2)

i think a but i can be wrong

2. See http://www.jiskha.com/display.cgi?id=1275520227 for the first post.
For the second post, the choice is correct.
(4y-1)(4y-2)
=16y² - 4y - 2(4y) + (-1)(-2)
=16y² -12y +2

2. Algebra (new one since I put "match" (bad speller)

I have a few match problems that I can't figure out. 1.solve: 3x+5=x√7 (that's a radical sign) 2.factor: (2k+3)2-(2x+3)(y-2)-20(y-2)2 (the "2" after (2k+3) ans (y-2) is suppose to be a square sign. thanks if you can help, or

Use Pascal's triangle to expand the expression. (x − y)5 so I tried to work this out: (x-y)^5 = [(x-y)(x-y)][(x-y)(x-y)](x-y) (x-y)^2 = (x-y)(x-y) = x^2 - 2xy + y^2 x^2 - 2xy + y^2)(x^2 - 2xy + y^2) = x^4 -4x^3y + 6x^2y^2 -

Simplify (2xy^2+3)((2xy^2)^2-(2xy^2)(3)+(3)^2) This reminds me of (U+a)(U^2- aU + a^2). When mulipltiplied out, one gets a cubic equation. Do you remember the formula for factoring the sum of two cubes? a^3+b^3= ????

Can 2xy - y - 1 be factored out? How? about all you can do is take the common y out of the first two terms; that in itself is not much help. dont know if this is rite or not..but just a guess.. assuming 2xy - y - 1 = 0 2xy - y = 1
