Answer 1

Answer:

Exercise– 2.1

1. Which of the following expressions are polynomials in one variable and which are not? State reasons for your answer.

Ans. (i) 4x2 – 3x + 7

⇒ 4x2 – 3x + 7x°

∵ All the exponents of x are whole numbers.

∴ 4x2 – 3x + 7 is a polynomial in one variable.

(ii)

∵ All the exponents of y are whole numbers.

∴ is a polynomial in one variable.
