Question

Which expressions are polynomials?

Select each correct answer.
4x
6y2 + 5x
7y2+9x

Answer 1

Im pretty sure it’s 7y2+9x /: 6y2+5x

Answer 2

4x

Explanation:

The polynomial expression is in the form:

f(x) = aₙxⁿ + aₙ₋₁xⁿ⁻¹ + aₙ₋₂xⁿ⁻² +..... + a₀

Polynomial have one variable so,

6y² + 5x

7y² + 9x

are not polynomial

Also since 4x is satisfying the expression of polynomial, Thus it is only polynomial in the given set of options.
