=>>Subtract from :-it means we have to subtract first value from those value which is written after from.

e.g->>2 from 4 =4-2 =2.

$= > 5ab - 2bc - 2ca - (2ab - 3bc - 7a)$

$= > 5ab - 2bc - 2ca - 2ab + 3bc + 7a$

=>Taking like terms together to make our calculation easier:-

$= > 5ab - 2ab - 2bc + 3bc - 2ca + 7a$

=>taking b and a from both equation :-

$\bold{\red{= >( 3a + c )b- a(2c - 7)}}✓$
