vaibhavlspise2001: only 4
vaibhavlspise2001: tahnk you
blessy96: one doubt
vgnidhis542: no if its only this then -4 is the answer
blessy96: for cubic polynomial
vgnidhis542: because it has 3 zeroes and the last one would be like -d/a...am i right????
blessy96: thinking same
blessy96: k anyway thank for answer mate
blessy96: and thanks @vgnidhi

Let \: the \: zeroes \: of \: the \: given \: cubic \: polynomial \: be \:   \\  \alpha,  \beta  and \: \gamma . \\ Now \: the \: given \: equation \: is \: 2 {x}^{3}  - 5 {x}^{2}  - 14 + 8

We \:  know \: that \:  \alpha  \beta  \gamma  =  \frac{ - d}{a}  \: for \: a \: standard \: cubic \: polynomial \\ i.e. \: a {x}^{3}  + b {x}^{2}  + cx + d

Here \:  a =2 \: and \: d = 8 \\ So, \:  \alpha  \beta  \gamma  =  -  \frac{8}{2}  =  - 4.

So, the answer is -4.
