Question

the process of adding two polynomials involves aligning
__________ terms and combining their
coefficients.

when subtracting polynomials, one must first
__________ the signs of the terms in the second
polynomial.

a polynomial with two terms is specifically called a
__________.

Explanation:

1. To add polynomials, you align terms with identical variable and exponent combinations (like terms) to combine their coefficients.
2. Subtracting polynomials is equivalent to adding the additive inverse, so you first flip/change the signs of all terms in the second polynomial.
3. A polynomial with exactly two distinct terms is defined as a binomial.

Answer:

1. like
2. change
3. binomial
