Question
Common factor of $ 12 a^2 b^2+4 a b^2-32 $ is 4.
✓
Answer
True.
Solution:
As we have,
$ 12 a^2 b^2+4 a b^2-32 $
$ =2 \times 2 \times 3 \times a \times a \times b \times b+2 \times 2 \times a \times b \times b-2^2 \times 2^3 $
$ =4\left(3 a^2 b^2+a b^2-8\right) $
Thus, the common factor is 4.
