x^(4)+x^(2)+1

The factor of x^8 + x^4 +1 are (A) (x^4 + 1 - x^2), (x^2 +1 +x), (x^2 + 1 - x ) (B) x^4 + 1 -x^2 , (x^2 - 1 + x), (x^2 +1 + x) (C ) (x^4 - 1 + x^2, (x^2 - 1 + x), (x^2 + 1 + x) (D) (x^4 -1 + x^2), (x^2 + 1 - x), (x^2 + 1 +x)

(x+4)/ ((x^(2)-4)(x+1))

Lt_(x to (1)/(2))((x)/(2x-1)-(2x)/(4x^(2)-1))=

Express (7x^(2)+4x+4)/((1-x)(2x^(2)+1)) in partial fractions.

(2x + 1) / (x) + (4x) / (2x + 1) = 5

4x^(2) - 4x + 1 = ("__________")^(2)
