The product of a monomial and a binomial is always a ________.

• A. monomial
• B. trinomial
• C. binomial
• D. constant

Answer 1

The correct option is C

binomial

The product of a monomial and a binomial always gives a binomial.

For example, let us multiply
$5x\text{(a monomial)}\text{by}(5x+4)\text{(a binomial.)}$

$5x(5x+4)=5x\times 5x+5x\times 4=25x^2+20x$

$25x^2+20x\text{is a binomial.}$
