Re: Which quadratic equation has roots of 4 and 1/2 ? [#permalink]
Slightly confused here on why Option C also isn't a correct answer choice:

2x^3−9x^2+4x=0
Divide both sides by x and this is same as Option B:
2x^2−9x+4=0

Given B satisfies the roots, shouldn't C satisfy as well?

Carcass.

Because C is NOT a quadratic equation The degree of the variable must max 2
