Project 17: Multiplying Polynomials

The length of this rectangle is expressed as 2x + 5.  The width is expressed as x + 8.

The area of the rectangle can be expressed as (2x + 5)(x + 8) = 2x^2 + 21x + 40

Explanation:

When X = 1, the length is 2*1 + 5 = 7

When X = 1, the width is 1 + 8 = 9

When X = 1, the area is 7*9 = 63

When X = 1, the area is 2(1)^2 + 21(1) + 40 = 2 + 21 + 40 = 63

When X = 2, the length is 2*2 + 5 = 9

When X = 2, the width is 2 + 8 = 10

When X = 2, the area is 9*10 = 90

When X = 2, the area is 2(2)^2 + 21(2) + 40 = 8 + 42 + 40 = 90

Project 17: Variables 'co' and 'co2' have been initialized.   These arrays represent the coefficients of two polynomials.

Task: To correctly assign the value of 'prod' which corresponds to the product of the polynomials with coefficients 'co' and 'co2'.

How to add to an array:

x.push(3);

x.push(5);

x.push(4 + 4);

//x would store the array [3,5,8].  The push command adds the value to the end of the array.
