How to find reminder and quotient of equation
Reminder Theorem Statement : if f(x) is a polynomial of degree m in x, then the reminder in the division of f(x) by x-α is equal to f(x) . Proof : By Euclid ’s or division algorithm we can find, the polynomial q(x) and r(x) such that f(x)=(x-α)q+r(x) . Where either r(x)=0 or the degree of r(x) is less than g(x)(x-α) . Therefore r(x)=0 or the degree of r(x) is less than “1” or will be equal to “0” . In the second case r(x)=k(constant) i) f(x)=(x-α)q(x)+k put x=α (x)=(α-α)q(x)+k f(α)=k ; Factor theorem If “α” is the root f(x)=0 then x-α is factor of f(x) Proof: f(x)=(x-α)q(x)+k --> (1) Put x=α , f(α)=k Put f(α)=0 , “α” is a root of the equation f(x)=0 => k=0 ; Substituting => f(x)=(x-α)q(x) v x-α is a factor of f(x) ; Fundamental theorem of Algebra Every polynomial equation of degree n ≥ 1 has at least one or real or imaginary.
