Zeros of polynomials: The value of a polynomial at is obtained by putting in and is denoted by. On putting in given polynomial , we get This implies. Important observations : i Every linear polynomial has one and only one zero. Let be a linear polynomial, then means. Take iv A polynomial can have more than one zero.

This remainder is the dividend now and divisor will remain same Again repeat from the first step, until the degree of the new dividend is less than the degree of the divisor. You might also like.

The method of factorisation worked for Division of a polynomial by a linear expression quadratics whose solutions are integers or rational We can apply the same principles in arithmetic to numbers. The dividend is divided by the divisor. The result is the quotient and the remainder is what is left over.

The most valuable use of this discovery is to determine if the divisor x - a is a factor of the dividend. If x - a is a factor of f x , the remainder will be zero.

You can quickly make this determination by plugging a into f x to see if the result is zero. This special use of the Remainder Theorem to determine a factor is call the Factor Theorem :. The factor theorem links factors and roots zeros of a polynomial. Let's take a look at some example questions:. When working with Synthetic Division , we saw a series of division problems involving a divisor of the form x - a , where the degree of the divisor was one.

Hint: Refer to Example 6. Page 3. Page 3 Section. Remainder Theorem. Factor Theorem. If the polynomial f x is divided by x — c.
