You take the three zeros and put them back with the x s
(x-6)(x+5)(x-2) they are reversed when you put them back in
multiply the first two and get [tex]x^2+5x -6x-30(x-2)[/tex]
simplify to [tex]x^2-x-30(x-2)[/tex]
Multiply it out again and get [tex]x^3-x^2-30x-2x^2+2x+60[/tex]
finally simplify and get [tex]x^3-3x^2-28x+60[/tex]
So the answer is the first one
