Best ResponseYou've already chosen the best response.0you could make 16y^4 the common denominator and add up the terms the denominator is a perfect square. Does the numerator factor?

Best ResponseYou've already chosen the best response.0rearrange as 16 y^8 + 8 y^4 + 1 if you let y^4 = x, this is also 16x^2 + 8x +1

Best ResponseYou've already chosen the best response.0is that =0 because what happened to common denominator

Best ResponseYou've already chosen the best response.1is it not true to say\[(y^2+\frac{1}{4y^2})^2=y^4+2(y^2)(\frac{1}{4y^2})+\frac{1}{16y^4}=y^4+\frac{1}{2}+\frac{1}{16y^4}\]
