spencer is asked to factor the polynomial 256x^4 y^2-y^2completely over the integers. his work is shown below.
256x^(4)y^(2)=y^(2)(256x^(4)-1)y^(2)(256x^(4)-1)=y^2(16x^(2)+1)< br />did spencer factor the polynomial completely over the integers? why or why not?
a. spencer did factor the polynomial completely; he identified teh gcf and applied the difference of cubes method.
b. spencer did not factor the polynomial completely; 16x^(2)+1 can eb factored over the integers.
c. spencer did not factor the polynomial completely; 16x^(2)-1 can be factored over the integers.
d. spencer did factor the polynomial completely; he identified teh gcf and applied the difference of squares method.

False because C)

Step-by-step explanation:

Our original function is

The first step we go is to take as GCF and take it out of bracket

also and and

Hence we can write the above equation as

Now we apply the differences of the square in this which says

Again applying the differences of the square in the first factor we get

Hence

Hence

Spencer did not factor the polynomial completely over the integers because Spencer did not factor the polynomial completely; 16x^(2)-1 can be factored over the integers.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
