Final answer:
To find the GCF (Greatest Common Factor) of the expression 3r³+12r²+2r+8, factor the terms and find the common factors. The GCF is r.
Step-by-step explanation:
To find the GCF (Greatest Common Factor) of the expression 3r³+12r²+2r+8, we need to factor the terms and find the common factors.
Step 1: Factor out the GCF of the coefficients, which is 1.
Step 2: Factor out the GCF of the variables, which is r.
Step 3: Find the common factors among the terms.
The GCF of 3r³+12r²+2r+8 is 1*r = r.
