Quadratic equation trick (without solving)

Quadratic equation trick without solve (for some spacific condition of sign)

frnds QE can give u 5 marks other qs in Quantative part is too much calculative but QE is very easy when u use tricks i provided in past some tricks but this is new one

follow only signs
if Q have sign (- -) or (+ -) without solve ans will definatly No relation
i.e.
ax2 - bx - c = 0
ay2 + by - c = 0 ans No Relation
or
ax2 + bx - c = 0
ay2 + by - c = 0 ans No Relation
or
ax2 - bx - c = 0
ay2 - by - c = 0 ans No Relation

and when sign have + + and - + then ans will - + > + +
ax2 + bx + c = 0
ay2 - by + c = 0 ans Y>X

try to solve Qs of this sign types Qs
