Question

Which of the given expression are polynomials in one variable and which are not? State reasons for your answer. 4x²-3x+7, y+²/y, x¹⁰+y³+t⁵⁰.

Answer 1

Hope this will help you........

4x^2 - 3x + 7, is a polynomial in one variable because it contains a single variable i.e. x.

y + 2/y is also a polynomial in one variable as it contains a single variable variable i.e. y.

x^10 + y^3 +t^50 is not a polynomial in one variable because it contains three variables..
