Given cubic polynomial is
Let assume that
Now, we have to find the zero of this cubic polynomial using hit and trial method.
Let assume that x = - 1
We know
Factor theorem states that if a polynomial if more than 1 degree f(x) is such that f (a) = 0, then x - a, is factor of f(x).
So, By factor theorem,
So, by using Synthetic Division Method, we have
Now, By Division Algorithm, we have
Dividend = Divisor × Quotient + Remainder
So,
Hence,
