1.	Which of the following expressions are polynomials in one variable and which are not ? Give reasons for you answer. (i) 3x ^(2) - 2x + 5 (ii) x ^(2) + sqrt2 (iii) p^(2) - 3p +q (iv)y + (2)/(y) (y ne 0) (v) 5 sqrtx + x sqrt5 (vi) x ^(100) + y ^(100)
Answer» Answer :(i) polynomial (ii) Polynomial (iii) No because it has two variables (iv) Not polynomial because EXPONENTS is negative. (v) Not polynomial because exponent of XIS not a non negative INTEGERS. (vi) Not polynomial in one variable becaue it has two variables.
