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.
