Answer 1

Answer:

$\boxed{\text{Degree = 4; Max. no. of terms = 5}}$

Step-by-step explanation:

(x² + x + 2)(x² – 2x + 3)

1. Degree of product

The degree of the product of two polynomials is the sum of their degrees.

Each polynomial is of degree 2, so the degree of the product is 4.

That is, the term of highest degree must come from x² × x² = x⁴.

2. Maximum number of terms

The maximum number of terms is one more than the degree of the product.

Thus, there is a maximum of five terms in the product: one for each power of x plus a constant term.

P = a₁x⁴ + a₂x³ + a₃x² + a₄x + a₅
