Option A
The GCF of the expression [tex]3 a^{2}+9[/tex] is 3
Solution:
Need to find GCF of the expression [tex]3 a^{2}+9[/tex]
Since only one expression is given it means we need to find G.C.F between two terms
Two terms are [tex]3a^2[/tex] and 9.
On factorizing each term we get
[tex]\begin{aligned} 3 a^{2} &=3 \times a \times a \\ 9 &=3 \times 3 \end{aligned}[/tex]
So greatest common factor between two term is 3.
so expression can be rewritten as [tex]3\left(a^{2}+3\right)[/tex]
GCF of the terms in an expression helps us in factorization of the expression.
Required solution of G.C.F of expression [tex]3 a^{2}+9[/tex] is option A. that is 3
