Answer 1

@sammixboo @whpalmer4 @Nnesha @peachpi

Answer 2

\[\huge\rm \frac{ 15xy }{ x^2-y^2} - \frac{ x-y }{ x+y }\]
like this ?

Answer 3

if yes
remember difference of square \[\huge\rm a^2 -b^2 = (a+b)(a-b)\]
2nd step ) find common denominator

Answer 4

3rd) cancel some stuff
4th) done!

Answer 5

so x ^2 - y^2 = ???

Answer 8

difference of square^

Answer 9

(x+y)(x-y)?

Answer 10

yes right!

Answer 11

now find common factor

Answer 12

\[\huge\rm \frac{ 15xy - (x-y)(x+y)}{ (x+y)(x-y) }\]
now solve
x+y are same at both denominator so just write on time and x-y is a common denominator
multiply top part with( x+y)
denominator of first fraction is same as common denominator so t 15xy stay same

Answer 13

got it ??

Answer 14

now just solve the numerator
