Question

construct the equation whose roots are 5 and -4

Answer 1

i hope it wii help u

Answer 2

now we know that Sum of roots:- alpha+beta=
-b/a
now product of roots = c/a
now let us assume 5 as alpha and -4 as beta
now alpha+beta=5-4=1
now alpha×beta = 5×(-4)=-20
now we know that:-

K [x^2-(alpha+beta)x +(alpha×beta)]
K[x^2-x-20] or x^2-x-20 where K is any non-zero constant.
