verify the relationship b/w the zeroes and coefficients[3x square plus 4x -4] |
| Answer» p(x)=3x^2+4x-4 here a=3,b=4 and c=-4 ( by comparison with ax^2+bx+c) for x=0p(x)=o3x^2+4x-4=03x^2+6x-2x-4=03x(x+2)-2(x+2)=0(3x-2)(x+2)=0therefore x=2/3 or x=-2let,alpha=2/3beta=-2now, alpha+beta= -b/a 2/3-2=-4/3 -4/3=-4/3similarly,alpha x beta= c/a2/3 x -2 = -4/3-4/3 = -4/3hence verified | |
