When simplifying a rational fraction, why do you need to factor the numerator and the denominator?
If there is a common factor in both the numerator and denominator, that factor will cancel, thus simplifying the fraction.
e.g.
15/18 = (3*5)/3*6)
=(3/3)*(5/6)
=(1)*5/6
=5/6

6y  y^22724 well it should simplify to (6y)/(y^1) which then changes to y(6y) which then equals y(6y)=0 then you set both parts equal to zero and solve for xero y=0 and/or (6y)=0 so y=0 or y=6 Did you mean for this …

How do you do?: x^2+1  x^41 Thanks! Try to factor wherever you can so you can reduce as much as you can. Factors of x^4  1 are (x^2 + 1)(x^2  1). Now we have: x^2 + 1  (x^2 + 1)(x^2  1) Do you see a common
