Degree of polynomial x^3-2) (x^2+11)​

Answer 1

Answer:

(x³-2) (x²+11)

=x³(x²+11) -2(x²+11)

=x⁵+11x³ -2x² -22

The highest power is the degree of the polynomial.

Hence,5 is the degree of the polynomial.

Hope it helps you.

Answer 2

Quintic

Step-by-step explanation:

(x³ - 2)(x² + 11)

= [(x³)(x²) + (x³)(11)] - [(2)(x²) + (2)(11)

= [x⁵ + 11x³] - [2x² + 22]

= x⁵ + 0x⁴ + 11x³ - 2x² + 22

hence it has 5 degrees and it is known as Quintic polynomial.
