If they are collinear, hence they lie on the same line..,

If they are collinear, hence they lie on the same line..,hence they are solutions of a same equation.,

If they are collinear, hence they lie on the same line..,hence they are solutions of a same equation.,let the equation be, $ax^{2} + bx + c = 0$

If they are collinear, hence they lie on the same line..,hence they are solutions of a same equation.,let the equation be, $ax^{2} + bx + c = 0$let the values of a and b be, 3 and -1,

If they are collinear, hence they lie on the same line..,hence they are solutions of a same equation.,let the equation be, $ax^{2} + bx + c = 0$let the values of a and b be, 3 and -1,therefore, the equation is $3x^{2} -x +c =0$
