Question

EXERCISE 2.1
Which of the following expressions are polynomials in one variable and which are not?
State reasons for your answer.

$(i) \: \\y + \frac{2}{y}$
$(ii) \: \: x ^{10} + y ^{3} + t ^{50}$
​

Answer 1

Step-by-step explanation:

y+ 2/y = y + 2y^-1

No, it is not a polynomial as power of variable" y" is negative integer.

Now,

x¹⁰ + y³ + t ⁵⁰

It is a polynomial but of three variable denoted by p(x,y,t)
