#### Answer

a., 3

#### Work Step by Step

Recall that the degree of a polynomial is the largest degree of all its terms.
For the product of $(3x-1)(4x^{2}-2x+1)$, we can find the term with the largest degree by multiplying the term from each individual polynomial that has the largest degree within that polynomial.
For example, $3x$ is the term from the first polynomial with the highest degree and $4x^{2}$ is the term from the second polynomial with the largest degree.
$3x\times 4x^{2}=12x^{1+2}=12x^{3}$, so the product of $(3x-1)(4x^{2}-2x+1)$ will be a polynomial of degree 3.
