Question

Can somebody explain how my online math course got from (x2 - y2) / (2x2 + 2xy + x + y) times (2x2 - 5x - 3) /(x2 + 3x) to (x-y)(x-3)/[x(x+3)]?

Answer 1

im guessing x2 means x^2

Answer 2

?

Answer 3

first term.
top :
(x^2-y^2)=
(x+y)(x-y)
bottom:
(2x+1)(x+y)

2nd term
top:
(2x+1)(x-3)
bottom:
x(x+3)

so all together its
(x+y)(x-y) (2x+1)(x-3)
---------- * ----------
(2x+1)(x+y) x(x+3)

cancel what cancels
and u should get ur answer

Answer 4

I typed it it wrong I think....I did not do the exponent thing where it's needed..gotta repost it...

Answer 5

2^2 would equal 2 squared, right?
