1. 1 , 2 , 3 , 4 are polynomial having one variable

5 is not because it has 2 variables x and y ! hope it helps you

thanks for raising beautiful question and marking brainliest

2. Given :  expressions

To Find :  Which of the following expressions are polynomial in one variable and which are not

1)4×2-3x+7

2)y2+root 2

3)3root t + t root 2

4)y+2/y

5)x10+y3+t50​

Solution:

4x²  – 3x + 7  is  quadratic polynomial in one variable x

y² + √2  is  quadratic polynomial in one variable y

3√ t + t√ 2  not  a polynomial as t is in  square  root

y + 2/y     not  a polynomial as  y is in fraction

x¹⁰ + y³ + t⁵⁰     has 3 variables

hence not a  polynomial in one variable
