Multiplying Polynomials Worksheets

What are Polynomials?

Polynomials are mathematical expressions that consist of variables and coefficients, combined using addition, subtraction, and multiplication operations. They can have one or more terms, where each term is a combination of variables raised to different powers.

Multiplying Polynomials

Multiplying polynomials involves multiplying each term of one polynomial with every term of the other polynomial. This process is often referred to as the distributive property of multiplication. To perform this operation, you need to multiply each term of the first polynomial with all the terms of the second polynomial, and then combine like terms, if any.

Steps to Multiply Polynomials

1. Multiply each term of the first polynomial with every term of the second polynomial.
2. Combine like terms, if any, by adding or subtracting them.
3. Simplify the resulting expression if possible.

Example:

Let’s consider the multiplication of two polynomials: (2x + 3) and (x – 4).
1. Multiply the first term of the first polynomial (2x) with each term of the second polynomial (x and -4):
– (2x * x) = 2x^2
– (2x * -4) = -8x

2. Multiply the second term of the first polynomial (3) with each term of the second polynomial (x and -4):
– (3 * x) = 3x
– (3 * -4) = -12

3. Combine the like terms obtained in steps 1 and 2:
– 2x^2 + (-8x) + 3x + (-12) = 2x^2 – 5x – 12

Therefore, the product of (2x + 3) and (x – 4) is 2x^2 – 5x – 12.
