Question

which of the following expressions are polynomials in one variable and which are not state reasons for your answers. if the given expression is a polynomial, sate whether it is a polynomial in one variable or not :(1)x^2-8x+15​

Answer 1

Answer:

4x2− 3x + 7 and y2+ √2 expressions are polynomials in one variable whereas, 3√t + t√2, y + 2/y, and x10 + y3 + t50 expressions are not polynomials in one variable.

Answer 2

(1)x^2-8x+15

Yes this statement is a polynomial because it has more than 2 terms.

It is a polynomial in one variable because this expression contains only 'x' as the unknown value/variable.
