Answer:
[tex]c^2d^2(c^2 + d)[/tex]
Step-by-step explanation:
The equation is [tex]c^4d^2 + c^2d^3[/tex] so we see that the highest number on both terms that we can factor out is 2. If we factor out [tex]c^2d^2[/tex] from both terms, we end up with [tex]c^2d^2(c^2 + d)[/tex], making [tex]c^2d^2[/tex] the GCF of this expression.
