If -1 and 2 are two zeroes of the polynomial 2/

1.	If -1 and 2 are two zeroes of the polynomial 2/
Answer» Given polynomial is p(x) = 2x3\xa0- x2- 5x - 2\xa0and -1 and 2 are zeroes of polynomial.{tex}\\therefore{/tex}\xa0{x - (-1)} (x - 2)= ( x + 1) (x - 2) = x2 - 2x + x - 2 = x2- x - 2 is a factor of p(x)For other zeroes, 2x\xa0+ 1 = 0{tex}\\Rightarrow x = \\frac { - 1 } { 2 }{/tex}{tex}\\therefore{/tex}\xa0Other zero = {tex}\\frac { - 1 } { 2 }{/tex}
