Question

A quadratic equation with integral coefficient has integral roots .Justify your answer

Answer 1

false..
frnd consider the givn  Quadratic equation...
8x2 - 2x -1 = 0
by splitting the middle term, 
8x2 -4x + 2x -1 = 0
4x(2x-1)+1(2x-1)=0
(4x+1)(2x-1)=0
if 4x+1 =0
THEN , x = -1/4
if 2x-1 =0
then, x = 1/2
therefore, x = -1/4 , 1/2
so the givn equation has integral coefficients but no integral roots.
hence the givn statemnt is false.


hope it can help u:)
