if the denominator is the same, then simplify the numerator.crappiefisher26 said:I have never done a question like this.
It says Adding Rational Expressions with a Common Denominator
Express the following sum as a single fraction.
> the 6z is also negative in the 1st equation-(8z-4y)/6z - (7z+y)/6z
Has this not been covered in class?crappiefisher26 said:I have never done a question like this.
"Rational expressions" are just polynomial fractions, so you'd work with them in the same way you would numerical fractions.crappiefisher26 said:It says Adding Rational Expressions with a Common Denominator
Is the first "minus" a negative sign, or a divider between your comment and the first expression? If the denominators are negative, shouldn't there be "minus" signs on them? Such as:crappiefisher26 said:the 6z is also negative in the 1st [expression]-(8z-4y)/6z - (7z+y)/6z
Does the variable "z" not then belong in the denominators?crappiefisher26 said:the denominators are -6 and 6
Thank you.crappiefisher26 said:heres the equation the right way.
[-(8z-4y)/(-6z)] - [(7z+y)/(6z)]
Note: An "equation" contains an "equals" sign, and is "solved". You have posted an "expression", to be "simplified".crappiefisher26 said:ok guess i was wrong with the equation
If the "minus" sign is on the entire expression, then it can be moved onto the numerator (standard practice) or onto the denominator (non-standard), but not both.crappiefisher26 said:- (2x-u)/(6x) + (8x+9u)/(6x)
for example -1/4 the negative is in lign with the divided by sign
With which? You have been provided with most of the worked solution to the posted exercise. If you are asking for assistance with the new expression (which should then have been posted as a new thread), then please reply showing how far you have gotten. (You can model your work on the solutions posted earlier.)crappiefisher26 said:help please
