Adding and Subtracting Rational Expressions
posted by mike .
Iwouldhighly appreciate it if someone could solve these forme.I think I typed themout correctly. What I'm looking at,for instance,the first one,is displayed 5n over 3 times 4n over 3
4.(5m+8/[m-1]) - (m-3/[m-1])
5.(x^2/[x-1]) - (1/[x-1])
7.(x^2+3x+2/[x^2-16] + (3x++6/[x^2-16])
8.7/(x-5) - (2+x/[x-5])
First, "(5n/3)- (4n/3)" is not "5n over 3 times 4n over 3."
If the fractions have the same denominator, just do the required operations in the numerator.
(5n/3)- (4n/3) = n/3
Use the same principle for the remaining problems.
I hope this helps. Thanks for asking.
