Since -5 and 4 are zeroes of the equation therefore (x+5) and (x-4) r the factors...
now equation is
(x+5)(x-4)=x^2+5x-4x-20=x^2+x-20
therefore the required equation is x^2+x-20
hope this helps u:p

X^2+X-20 is the answer.
2nd term =Alfa+Beta= -1
Last term =Alga×Beta= -20
2nd term =Alfa+Beta= -1
Last term =Alga×Beta= -20
Plz forgive me as it is +X instead of -X
