Part a: create an example of a polynomial in standard form. how do you know it is in standard form? part b: explain the closure property as it relates to polynomials. give an example.

part a : a polynomial is in standard form if 1. the exponents of x are descending 2. no negative exponents for x example: x^2 + x + 3

part b : the closure property polynomials are 'closed' under addition and multiplication because if you add two polynomials, or multiply two polynomials , you get another polynomial.

example: suppose we are given the polynomials 3x2+2x+7 and 4x+1.

if we add them we get

(3x2+2x+7)+(4x+1)=3x2+6x+8

the sum is a polynomial. this is an example of closure of polynomials under addition.

if we multiply them we get

(3x2+2x+7)⋅(4x+1)=12x3+11x2+30x+7

the product is a polynomial. this is an example of closure of polynomials under multiplication.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
