Would you please re-check your question?
As per the question -3 is the Zeroes of the given polynomial.
If we simply the given polynomial,i.e. 2x³+3x²-5+11x-6 = 2x³+3x²+11x-11
If we put -3 in the equation,
2(-3)³+3(-3)²+11(-3)-11
= -54+27-33-11
=-27-44
=-71≠0
But in any case it should be equal to zero as -3 is one of the zeroes of the equation.
