Question: http://i46.photobucket.com/albums/f1...9/untitled.jpg
sub in x=2 and solve to find k
Once you've got k factorise the cubic to get (x-2)(some quadratic)=0 and then solve the quadratic.
well how do u factor the cubic function, do u use quadratic formula? Sry i just completely forget.
You could divide the cubic by x-2.
nvm i figured it out, thanks for the help
