Find the zeroes o

Answer :

x2 – 3x – 10 = 0


x2 – 5x + 2x – 10 = 0


x(x - 5) + 2(x – 5) = 0


(x + 2) × (x – 5) = 0


x = -2, 5


Let α = -2 and β = 5


So the relationship between zeroes and coefficient are:



Taking 1st equation,


LHS = α + β = 3


RHS


So, LHS = RHS


Taking 2nd equation,


LHS = α β = -10


RHS


So, LHS = RHS


Hence, the relationship is verified.
