What are Like Terms What are Unlike Terms ? How to subtract Like Terms ? While subtracting one monomial from another monomial, we only do the subtraction of numeric parts or constant and keep the variable part as such. Here we must note that one monomial is subtracted from other monomials when both have like terms. Or we can also say that: Subtraction of Monomials having unlike terms is not possible, when they have unlike terms E.g. Monomials 10x can be subtracted from 32x because both have like terms While monomials 10p cannot be subtracted from 32q because both have unlike terms. Subtraction of Monomials with like terms is similar to subtraction of like terms. Let's understand subtraction of monomials from the following two examples: Example 1: Subtract 10ab from 12ab Solution: This proceeds as: 12ab - 10ab Subtract constants and keep variable as such & we get: = (12 - 10)ab Solve brackets and we get: = 2ab Hence, 12ab - 10ab = 2ab Example 2: solve (5x2 - 4x2) Solution: This proceeds as: 5x2 - 4x2 Subtract constants and keep variable as such & we get: = (5 - 4)x2 Solve brackets and we get: = 1x2 Or we can also write it as: = x2 Hence, (5x2 - 4x2) = x2
