Answer:
2r(d-2)
Step-by-step explanation:
1. 2 and r are both factors of the monomials 2dr and -4
2. Put it as 2r and divide each monomial and put it into parentheses.
3. 2dr/2r is "d" while -4r/2r is -2 since the r cancels out
3. After your done dividing each term b your GCF multiply your GCF to whatever is in the parentheses. 2r: GCF (d-2): Factors
2r(d-2)
