Answer 1

What are you trying to do?

Answer 2

factorise

Answer 3

\[[\frac{ (x-a) }{ (x-b) }+\frac{ (x-b) }{ (x-a) }] * \frac{ (x-b)(x-a) }{ (x-b)(x-a) }\]

Answer 4

congrats dan for being green!!!!!

Answer 5

Do that multiplication to make one fraction with the common denominator

Answer 6

it is not multiplication. it is equal

Answer 7

I can re-write your equation like this:
\[\frac{ (x-a)^{2} +(x-b)^{2}}{ (x-a)(x-b) }=\frac{ a ^{2} +b ^{2}}{ ab }\]
since I have added the fractions each other at left side and I have added the fractions each other at right side

Answer 8

Now, wat is the least common multiple, of that expression?

Answer 9
