Q.
Show that F(0)=1.
Dear student,
given
as we can see ............(1)
also ......................(2)
also ..........(3)
as we can see F(x) is a quadratic equation.and F(x)-1=0 is also a quadratic equation
as we can see from (1),(2),(3) x=a,b,c satisfy the equation.F(x)-1=0.
but quadratic equation has exactly two roots
here more than two values of x satisfies the equation.
so F(x)-1=0 is an identity.
it is satisfied by all values of x
F(0)-1=0 is also true
F(0)=1
enjoy
