  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
