Question

Simplify like terms of
1. 3a-2b-ab-(a-b+ab)+3ab+b-a​

Answer 1

$\red{ \sf Given:- }$

$\sf \red{ \mapsto3a - 2b - ab(a - b + ab) + 3ab + b - a }$

$\sf \green{Solution:- \: }$

$\sf \blue{ \mapsto (3a-a-a)+(-2b+b+b)+(-ab-ab)+3ab}$

$\sf \mapsto \purple{a+0+ab }$

$\sf \green{ \mapsto \: a+ab}$

${ \boxed { \sf \pink{ \mapsto \: a(1+b) }}}$

Thanks for question ☺️

Answer 2

=3a-2b-ab-a+b-ab+3ab+b-a

=(3a-a-a)+(-2b+b+b)+(-ab-ab+3ab)

=a+0+ab

=a+ab

=a(1+b)
