2 x^4 + x² + 22 x + 6 = 0 divide expression by 2 to get
x^4 + 0.5 x² + 11 x + 3 = 0
Possible values of rational roots /zeros : + 3 or -3 or + 1 or - 1
= factors of constant term
2x^4 + x^2 - 22 x + 8 = 0 divide by 2
x^4 + 0.5 x^2 - 11 x + 4 = 0
possible of zeros (rational values) : +1 -1 +2 -2 +4 -4
x^4 + 0.5 x² + 11 x + 3 = 0
