Homework Help: MATH(PLease Help)

Posted by margie on Thursday, March 8, 2007 at 9:52pm.

(y+2)/(y) = 1/(y-5)
Solve the rational expression.

Remember that if:

a/b = c/d


a * d = b * c

I believe in school they call this the fraction crossover rule or fraction cross rule or something like that.

i would work it like a proportion and cross multiply and then divide.
(y+2)/(y) = 1/(y-5)
(y-5)(y+2) = y
y^2-3y-10 = y
y^2-4y-10 = 0
Since there are no factors of 10 whose difference is 4, use the quadratic formula to solve.
