Given that the square of X plus 2X minus 1 equals 0, what is the square of X plus one-fourth of X equal to? Given that the square of X plus 2X minus 1 equals 0, how much is the fourth power of X plus one-fourth of the fourth power of X?

X2+2X-1=0
Divide both sides by x
X+2-1/x =0
X-1/x=-2
Square both sides simultaneously
X2+1/ x2=6
Square both sides simultaneously
X4+1/x4=34
