if alpha beta and gamma are the zeros of a cubic polynomial f(x) than
f(x) =k{xcube - ( alpha +beta+gamma) xsquare + (alphabeta+betagamma+gammaalpha) x - alphabetagamma}
where K is any non zero real number
hair alpha + beta + Gamma is equal to 2, alpha beta + beta gamma +, Alpha is equal to minus 7 and alpha beta gamma is equal to minus 14
therefore f(x)= k(x cube minus 2 x square - 7 x + 14 ),where there is any non zero number
