Answer:
We cannot say it's different Difference ot of Two Cubes because 2d2 is not not cube it's square. and 8d is not a cube.
We cannot say Difference of Two Squares because only first term 2d2 has a square.
It is not a Perfect Square Trinomials because Perfect Square Trinomials appears as ax2 + bx + c, but the given ter doesn't follow this.
A. Common Monomial Factor can be regarded as a variable, or more than one variable that that is present in the polynomial terms.
Example is 4x2 + 16x,
If factorize we have 4x(x + 4) with monomer of 4x and polynomial of x + 4). that cannot be factorized into lower polynomial.
Hence 2d2-8d can be factor as 2d(d-4) where 2d is the monomer and (d-4) cannot be factorize into lower degree polynomial.
