Question

Which polynomial is not in standard from?
(i) $x^3+x^2-1=x^2+x^3$
(ii) $(x^4+1)(x-x^2)$
(iii) $x^6+x^3-x+1$

• A. (iii)
• B. (ii)
• C. (i) and (ii)
• D. (ii) only

Answer 1

The correct option is C (i) and (ii)

The standard form for writing a polynomial is to put the term with the highest degree first, then the term with the next highest degree, and so on.
So, $x^6+x^3-x+1$ is the standard from of the polynomial.
Therefore, (i) and (ii) are not the standard form of the polynomial.
