Answer:

All of them are polynomials because they all have variable, constant, coefficients, addition, subtraction, multiplication.

  • [tex]\mathrm{\:}5x^2+4x+1:\quad \mathrm{True}[/tex]

  • [tex]\frac{x^2-x-12}{x+3}-->x -4 : \quad \mathrm{True}[/tex]

  • [tex]5x^6-3x+4:\quad \mathrm{True}[/tex]

  • [tex]8x^{10}+2x^5:\quad \mathrm{True}[/tex]

Answer:

Option 3 :  is not polynomial

Step-by-step explanation:

Because in this division has occur

mathematical expression which  contains two or more algebraic terms which are added, subtracted, or multiplied (no division allowed!). Polynomial expressions include at least one variable and typically include constants and positive exponents at well.
