[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]
We have shown some expressions:
Binomial has two terms
A. 7x+21
It is a binomial.
B. 3/x
It is not a binomial.
C. 8x²+6x+5
It is trinomial as it has three terms
D. 19x⁴
It is monomial as it has only terms.
Thus, option (A) 7x+21 is the binomial as it has two terms option (A) is correct.
