## ridgeboy36 Group Title what is the simplified form of (5)/(3y+2)-(4)/(9y^2-4)? Any help with this problem would be greatly appreciated!!! one year ago one year ago

1. satellite73

start with $\frac{5}{3y+2}-\frac{4}{(3y+2)(3y-2)}$ then see that the last common multiple of the denominators is $$(3y+2)(3y-2)$$

2. satellite73

go to $\frac{5(3y-2)-4}{(3y+2)(3y-2)}$ and finish by multiplying out in the numerator, and combine like terms
