This question would never appear on the GMAT, so I wouldn't worry about it. The GMAT doesn't test cubic polynomials.
Private tutor exclusively for the GMAT and GRE, with over 20 years of experience.
Followed here and elsewhere by over 1900 test-takers.
I have worked with students based in the US, Australia, Taiwan, China, Tajikistan, Kuwait, Saudi Arabia -- a long list of countries.
My students have been admitted to HBS, CBS, Tuck, Yale, Stern, Fuqua -- a long list of top programs.

As a tutor, I don't simply teach you how I would approach problems.
I unlock the best way for YOU to solve problems.

Hi,

Sanju makes a lot of posts (I'm assuming you cross-posted this from the thread that he started) involving non-GMAT questions - I'd steer clear of them.

As already noted, there's no way this question would show up on the GMAT.
