Final answer:
To subtract the given polynomials, combine like terms by subtracting the coefficients of the corresponding variables.
Step-by-step explanation:
To subtract a polynomial from another polynomial, we need to combine like terms. Let's compare the given polynomials:
3ab - 4bc + abc
2ab + 3abc + 1
We can subtract them term by term:
(3ab - 2ab) - 4bc + (abc - 3abc) - 1
Combining like terms, we get:
ab - 4bc - 2abc - 1
