Which polynomial is prime?
x2-36
x2-16
x2-7x + 12
x2-x-20

Step-by-step explanation:

x^2 - 36 is the difference of two squares and factors as follows:

        (x - 6)(x + 6)

x^2 - 16 is the difference of two squares and factors as follows:

        (x - 4)(x + 4)

x^2 - 7x + 12 is an easily factored quadratic; the factors are

         (x - 3)(x - 4)

x^2 - x - 20 is an easily factored quadratic; the factors are

         (x - 5)(x + 4)

I conclude that none of the four expressions is prime.

B.

Step-by-step explanation:

We are asked to find the prime polynomial from our given choices.

We know that a polynomial is prime, when it has only two factors that are 1 and polynomial itself.

Upon looking at our given choices, we can see that each polynomial can be factored except .

We can see that is sum of squares and sum of squares cannot be factored, therefore, polynomial is a prime polynomial.

answer: x=3 and y=4

step-by-step explanation:

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
