Question

which is the following expression are polynomial in one variable and which are not,? State reasons for your answer 4x-3x+7

Answer 1

Here is your answer  4x-3x+7 is a polynomial in one variable as it only consists of one variable which is 'x'

Answer 2

4x^2-3x+7

= 4x^2- 3x^1+7×x^°

=where hole number is 0,1,2

= then expression is polynomial.

= therefore here is one variable x

So that polynomial is one variable
