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

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

    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
