Product of factors

I am finding it difficult to do this question.

A^2c - 16b^2c

I understand you need to get in the form
A^2c - 16b^2c

All i have is

ca^2 - 4^2cb^2

C(a)^2 - c(4b)^2

??
Please help

Assuming that you are trying to factorise the expression, take out a common factor of c and then you'll have a difference of squares.

Your question does not really make sense

Are you trying to factorise

a2c16b2ca^2c - 16b^2c

If that is the case then your c(a2(4b)2)c(a^2-(4b)^2) is correct

Do you know how to do Difference of 2 squares?
