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.

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.

The diagram is attached below.

Step-by-step explanation:

A normal distribution mean 0 and standard deviation 1 is known as the standard normal distribution.

So, the readings on the thermometers (denoted by Z) follows N (0, 1).

It is provided that 2.7% of the thermometers are rejected because they have readings that are too high and 2.7% are rejected because they have readings that are too low.

This implies that:

The value of z associated to both these probabilities are:

z = 1.93.

That is,

*Use a z-table.

The diagram for the two readings that are cutoff values separating the rejected thermometers from the others is attached below.
