How to get the factor in synthetic division?

If x - c is a factor, you can rewrite the original polynomial as (x - c) (quotient) . You can use synthetic division to help you with this type of problem. The Remainder Theorem states that f(c) = the remainder. So if the remainder comes out to be 0 when you apply synthetic division, then x - c is a factor of f(x).

How to find real zeros using synthetic division?

Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial . If the remainder is 0, the candidate is a zero. If the remainder is not zero, discard the candidate. Repeat step two using the quotient found from synthetic division.

How to find factors of a polynomial?

Step 1: Group the first two terms together and then the last two terms together. Step 2: Factor out a GCF from each separate binomial. Step 3: Factor out the common binomial . Note that if we multiply our answer out, we do get the original polynomial.

How to find zeros of a function?

The zero of a linear function can be found by replacing the y with zero and then solving for x . Quadratic functions are functions that can be put in the form f(x) = ax2 + bx + c, which is called the standard form. Graphically these graphs are parabolas. The zeros of the function are where the f(x) = 0.

How to find factors of a cubic equation?

Steps for Factoring Cubic Polynomials Step 1: Find a root, say 'a', of the cubic polynomial. Then (x - a) is the factor. (This can be one of the prime factors of the constant term of the polynomial) Step 2: Now, divide the linear factor by the cubic polynomial to find a quadratic factor of the polynomial.

What is the synthetic method in math?

The word “synthetic' is derived from the word 'synthesis which means to combine together. In this method we combine together a number of facts, perform certain mathematical operations and arrive at the solution . In this method we start with the known data and connect it with the unknown part.

Every number has at least two factors. To find other factors, start dividing the number starting from two and working your way up until you reach that number divided by 2 . Any quotient that does not have a remainder means that both the divisor and the quotient are factors of that number.

Is the Factor Theorem synthetic division?

The point of the Factor Theorem is the reverse of the Remainder Theorem: If you synthetic-divide a polynomial by x = a and get a zero remainder, then not only is x = a a zero of the polynomial (courtesy of the Remainder Theorem), but also x − a is a factor of the polynomial . (Why? It's courtesy of the Factor Theorem.)
