It is a tricky one.
Maybe before trying this one, have a go at
Can you do it?
9x^2y^2+5xy-4
I dont really even know where to begin
My book doesnt explain what to do with this kind of problem at all. I mean it does talk about factoring trinomials, but when its setup this way its a bit confusing, and different
any help is appreciated.
Ok so heres what I think I should do with that, if someone can fix my train of thought i think that would help me correct the errors.
9x^2y^2+9x-4x-4
add ()'s
(9x^2y^2+9x)(-4x-4)
(9x^2y^2+9x)
9x(y^2 + 1)-4(x+1)
this would be so much better if my book actually talked about factoring trinomials when you have exponents set up this way, outside the norm
i also tried something like this but it just didnt look right at all:
9(xy)^2+5(xy)-4
9xy(1^2 +1) -4(1(xy) +1)
