Question

m(x-y) - n(x-y) / m-n = ?

Answer 1

(m-n)(x-y)/m-n=x-y

Answer 2

1. factorise the numerator by taking out the common factor and group the rest of the terms
m(x-y) - n(x-y) =(m-n)(x-y)

2. rewrite the expression
m(x-y) - n(x-y) / m-n = (m-n)(x-y) /(m-n)

3. cancel the common factor in the denominator and numerator, that is(m-n)

4. you get the answer!~

Answer 3

Thanks!
