Question

who wants to rationalize some expressions :D?

Answer 1

not = but the answer is 3 after cancling

Answer 2

oo we're not even rationalizing. I meant just simplify rational expressions.

Answer 3

which mean x =0 ?

Answer 4

3 + x = 3 ?

Answer 5

factor then cancle

Answer 6

3xy/xy+x
xy+x factors to just x(y) right?

Answer 7

is the denominator (xy+x)

Answer 8

which would then cancle with the xy on top leaving only 3. yes dumb

Answer 9

\[\frac{3xy}{xy+x} = \frac{3xy}{x(y+1)} = \frac{3y}{y+1}\]

Answer 10

only the x cancels

Answer 11

hummmm..

Answer 12

Oh you ment 3xy/(xy+x) :)

Answer 13

when you factor something out, divide by each term
xy/x = y
x/x = 1

Answer 14

dumb would you look at another?

Answer 15

sure
