Factor out 8x^3y^6 + 27 One factor is 2xy^2+3. (The sum of the cube roots of the first and last terms). Use long division to compute (8x^3y^6 + 27)/(2xy^2 + 3) to get the other factor

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)(y2)20(y2)2 (the "2" after (2k+3) ans (y2) is suppose to be a square sign. thanks if you can help, or

factor completely. remember to look first for a common factor. if a polynomial is prime state this. x^2+2xy+y^29

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