if in equation Ax^2+Bx+c=0
A=C, then?
two roots α and β are reciprocal to each other

if in equation Ax^2+Bx+C=0,
B=0
two roots α and β are equal in magnitude and oposite in sign

in equation x^{2}+5x+6=0
the sign of two roots α and β is ???
 sign of (α and β)= ve
 sign of (αβ)= +ve
 both roots α and β are negative

in equation x^{2}5x+6=0
the sign of two roots α and β is ???
 sign of (α and β)= +ve
 sign of (αβ)= +ve
 so,both roots α and β are positive

in equation x^{2}5x6=0
the sign of two roots α and β is ???
 sign of (α and β)= +ve
 sign of (αβ)= ve
 then, α is positive and β is negative if α>β(numerically)

in equation x^{2}+5x6=0
the sign of two roots α and β is ???
 sign of (α and β)= ve
 sign of (αβ)= +ve
 then, α is negative and β is positive
 if, α>β(numerically)

roots of an equation is given by
x=(b±√D)÷2a
