48c^5 + 168c^4 + 147c^3

1. find a number that will divide evenly into all 3 coefficients, then take out the maximum number of "c" from each monomial

3c^3(16c^2+56c+49)

2. factor the equation inside the parenthesis - leaving the 3c^3 alone

3c^3(4c+7)(4c+7) then simplify

YOUR ANSWER --> --> --> 3c^3(4c+7)^2

Take out a common factor
3c3(16c2+56c+49)
Simplify the quadratic equation in the bracket.
3c3(4c+7)(4c+7)

the numerical coefficients have a common factor of 3; the lowest exponent on the common variable factors of c is 3, so factor out 3c^3:

3c^3 (16c² + 56c + 49)

the quadratic trinomial is a perfect square: 16c² is the square of 4c, 49 is the square of 7, and 56c is twice the product of 4c and 7, so

3c^3 (4c + 7)²

48c^5+168c^4+147c^3
=3c^3(16c^2+56c+49)
=3c^3[(4c)^2+2(4c)(7)+(7)^2]
=3c^3(4c+7)^2
A is the answer.
