Find the gcf of the expression.
3a²+9
a. 3
b. a
c. a+3
d. 3a

Option A

The GCF of the expression is 3

Solution:

Need to find GCF of the expression

Since only one expression is given it means we need to find G.C.F between two terms

Two terms are and 9.

On factorizing each term we get

So greatest common factor between two term is 3.

so expression can be rewritten as

GCF of the terms in an expression helps us in factorization of the expression.

Required solution of G.C.F of expression is option A. that is 3
