Question

Simplify : a + b –(2a + 3b + ab) + 6ab + (a – 4b – 2ab)

Answer 1

Given :

Simplify by combining like terms :–

$\sf{a + b - (2a + 3b + ab) + 6ab + (a - 4b - 2ab)}$

Solution :

$\sf{~~~~~~~~~~a + b - (2a + 3b + ab) + 6ab + (a - 4b - 2ab)}$

$\sf\implies{a + b - 2a - 3b - ab + 6ab + a - 4b - 2ab}$

$\sf\implies{(a - 2a + a) + (b - 3b - 4b) + (-ab + 6ab - 2ab)}$

$\sf\implies{(2a - 2a) + (b -7b) + (-3ab + 6ab)}$

$\sf\implies{{\green{\underline{\boxed{\bf{-6b + 3ab}}}}}}$

∴ Required answer :

$\sf{a + b - (2a + 3b + ab + 6ab + (a - 4b - 2ab)}$

$\sf{~~~~~~~~~~={\green{\underline{\underline{\bf{-6b + 3ab}}}}}}$

Answer 2

Answer:

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