Question

Hellow gyus plss tell how to cancel this...... In detail plss

Answer 1

ANSWER

the terms which are same in numerator and denominator are cancelled

since

(-a+b) is same as (a-b) if we multiply (a-b) by negative sign

so multiply both denominator and numerator by -1

we get

-ab(-a+b) / (a+b) (-a+b)

= -ab/(a+b)

if this really helpful

mark me as brainliest
