Question

Simplify:

$(v i)$ $8 a b c + 2 a b - 4 a b c + a b$

Open in App

Solution

$Step:$ Simplify the expression

By grouping the terms having the same literals and adding we get,

$8 a b c + 2 a b - 4 a b c + a b$

$= (8 a b c - 4 a b c) + (2 a b + a b)$

$= a b c (8 - 4) + a b (2 + 1)$

$= 4 a b c + 3 a b$

Hence, $8 a b c + 2 a b - 4 a b c + a b = 4 a b c + 3 a b$
