Question

Your answer should be a polynomial in standard form. (x + 5)(x +3)=(x+5)(x+3)

Answer 1

Answer:

∴(x+5)(x+3) =x²+8x+15

Step-by-step explanation:

Standard form of a polynomial:

Standard of polynomial means that the terms ordered from biggest exponent of variable to lowest exponent of variable.

Example:

$a_nx^n+a_{n-1}x^{n-1}+a_{n-2}x^{n-2}+......$

Given,

(x+5)(x+3)

=x(x+3)+5(x+3)

=x²+3x+5x+15

=x²+8x+15

∴(x+5)(x+3) =x²+8x+15

The degree of the polynomial is 2 and is a one variable polynomial.
