2a2(ab+3b)
2 a superscript 2 baseline left parenthesis a b plus 3 b right parenthesis

2a2b(a+3b)
2 a superscript 2 baseline b left parenthesis a plus 3 b right parenthesis

2a2(a+3b)

Answer 1

To factor the expression \(2a^3b + 6a^2b^2\) by finding the greatest common factor (GCF):

1. Identify the GCF of the terms:
- The coefficients are 2 and 6, and their GCF is 2.
- The variable part for \(a\) is \(a^2\) (the smallest power of \(a\) in both terms).
- The variable part for \(b\) is \(b\) (the smallest power of \(b\) in both terms).

Thus, the GCF is \(2a^2b\).

2. Now, divide each term by the GCF:
- The first term: \(2a^3b \div 2a^2b = a\)
- The second term: \(6a^2b^2 \div 2a^2b = 3b\)

3. Rewrite the expression using the GCF:
\[
2a^3b + 6a^2b^2 = 2a^2b(a + 3b)
\]

Therefore, the expression can be factored as:
\[
2a^2b(a + 3b)
\]

The correct response is:
**2 a superscript 2 baseline b left parenthesis a plus 3 b right parenthesis**.
