1 is C, since it is anything less than 8, so 7 times 2 is 14 minus 2 is 12.
2 is C, since it is anything less than 8, so 7 times 3 is 21, and 1 minus 21 is -20.
Complete 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:

Step-by-step explanation:
<em>See comment for complete question</em>
Given


Required
Determine how they can show if the products are the same or not
To do this, we simply factorize each polynomial
For, Polynomial A: We have:

Factor out 4x

Apply difference of two squares on x^2 - 4

For, Polynomial B: We have:

Expand x^2 + x - 2

Factorize:

Factor out x + 2

Factor out 4x

Rearrange

The simplified expressions are:
and

Hence, both polynomials are equal
