Question

Emily and Zach have two different polynomials to multiply: Polynomial product A: (4x2 – 4x)(x2 – 4) Polynomial product B: (x2 + x – 2)(4x2 – 8x) They are trying to determine if the products of the two polynomials are the same. But they disagree about how to solve this problem.

Answer 1

One way could be to factor each one

A:- = 4x(x - 1)(x - 2)(x + 2)

B:- = 4x ( x + 2)(x - 1) (x - 2)

This shows that the products are the same.

Answer 2

One way could be to factor each one

A:- = 4x(x - 1)(x - 2)(x + 2)

B:- = 4x ( x + 2)(x - 1) (x - 2)

This shows that the products are the same.
