Answer 1

Perform the indicated operation.

\[\frac{ r^2 }{r-s } - \frac{ s^2 }{ r-s }\]

Answer 2

ok so when you have a variable with a power and its being divided by the same variable you subtract the powers

Answer 3

r^2 is divided by `r-s` which is an expression not a single variable, so you can't apply the exponent rule here

Answer 4

find the common denominator

Answer 5

\[\rm \frac{ a }{ b} -\frac{c}{b}\]
denominators are the same
so `b` is the common denominator i would rewrite it as a single fraction
\[\rm \frac{ a }{ b} -\frac{c}{b}=\frac{a-c}{b}\]

Answer 6

Umm so basically there \[\frac{ r+s }{ r-s}\]

Answer 7

\[\frac{ r^2 }{r-s } - \frac{ s^2 }{ r-s }\]
how would you rewrite this as a single fraction??
what's the common denominator ?

Answer 8

single fraction hrmm r+s

Answer 9

i just want to know..how did you get `r+s` at the numerator ?
what was your next step after this
\[\frac{ r^2 }{r-s } - \frac{ s^2 }{ r-s }\]
?

Answer 10

Take (r-s) as LCM so you got r2-s2 at numerator
And we can also write r2-s2 as
(r-s)(r+s)

Answer 11

r2-s2/r-s
r-s(r+s)/r-s
answer will be r+s

Answer 12

Correct

Answer 13

O.mg. wait blocked you?
