Step-by-step explanation:
if given no are zeroes of polynomial, then
P(3) = 0
= 2(3)^3 - 3( 3)^2 -8( 3) -3
= 54 - 27 - 24 - 3
= 54 - 54
= 0
Yes , -3 is the zero of the above polynomial.
P(-1) = 2(-1)^3 -3(-1)^2 -8( -1) -3
= -2 -3 +8 -3
= -8 +8
=0
Yes , -1 is also a zero of the above polynomial.
similarly , -1 /2 is also a zero of the above polynomial.
