Question

Choose the correct method to factorize the following *

5hs-10hr-2ks+kr
a-Taking HCF common
b-Mid-term break
c-Algebraic Identities
d-Grouping

Answer 1

Algebraic identities

Explanation:

Here, we want to choose the correct method to factorize the given expression

That will be;

Algebraic identities

This is because, the terms which have an algebraic term in common have already been grouped and thus what we have to apply next is algebraic identities
