Question

Which of the following polynomials are binomials?

(1) p(x) = x + 1

(2) q(x) = $x^3+x$

(3)r(x) = $\sqrt{2}+x+x^2$

(4)r(u) = $u+u^2-2$

• A. 1
• B. 2
• C. 1 and 2
• D. 3

Answer 1

The correct option is C

1 and 2

Binomial is polynomial with two terms.

(1) p(x) = x + 1 – only 2 terms

(2) q(x) = $x^3+x$ – only 2 terms

(3) r(x) = $\sqrt{2}+x+x^2–3$ terms

(4) r(u) = $u+u^2-2–3$ terms.
