For example shows multiplication of the trinomials multiplied by a polynomial is the binomial or you about polynomial. Factor theorem if px is a polynomial in x and pa 0 then x a is a factor of px solving cubic equations we can use the factor theorem to find one factor of a cubic function and then use polynomial long division to find the remaining factors.

Polynomial long division examples with solution Dividing polynomials by monomials. Example of a polynomial. For example - x2 x 6 -1 x2 x 6 -lx 3x - 2.

X 2 2x 5. From the previous example we can verify the polynomial division algorithm as. Evaluate x 2 10x 21 x 7 using long division.

So we write the polynomial 2x 4 3x 2 x as product of x and 2x 3 3x 1. X 2 2 x 5 1 0 2 x 5. There are three types of polynomials namely monomial binomial and trinomial.
