ANSWER

The general form of cubic polynomial is p(x)=ax

3

+bx

2

+cx+d where x is a variable and a,b,c,d are constants. The first term of this polynomial has power 3, the second term of this polynomial has power 2 and the third term of this polynomial has power 1 and therefore, the degree of the polynomial is the largest exponent that is 3.

Similarly, in the polynomial p(x)=2x

3

−3x

2

−5, the first term of this polynomial has power 3 and the second term of this polynomial has power 2 and therefore, the degree of the polynomial is the largest exponent that is 3.

Hence, the polynomial p(x)=2x

3

−3x

2

−5 is a cubic polynomial.
