How do you factor polynomials using synthetic division?

How do you factor polynomials using synthetic division?

Synthetic division is another way to divide a polynomial by the binomial x – c , where c is a constant.

  1. Step 1: Set up the synthetic division.
  2. Step 2: Bring down the leading coefficient to the bottom row.
  3. Step 3: Multiply c by the value just written on the bottom row.
  4. Step 4: Add the column created in step 3.

Can you always use synthetic division for dividing polynomials?

We can only divide by a binomial whose leading coefficient is 1–thus, we must factor the leading coefficient out of the binomial and divide by the leading coefficient separately. Also, the binomial must have degree 1; we cannot use synthetic division to divide by a binomial like x2 + 1.

Can you factor polynomials on a graphing calculator?

To factor on a TI-84, you can use the Equation Solver function. To access it, press the MATH button on your calculator, then hit the up arrow to scroll directly to the bottom of the list. Press ENTER and input the equation. You can also add a custom program to your calculator to more easily factor polynomials.

Can you factor Trinomials on a graphing calculator?

Factoring trinomials can be carried out either by hand or by using a graphing calculator.

When should you use synthetic division?

Synthetic division can only be used if you’re dividing by a LINEAR factor in the form x – a. For example, it works if you are dividing by x – 3 or by x + 4. If you need to divide by a polynomial with a higher degree or one that doesn’t have a 1 as the leading coefficient, you’ll have to do plain old long division.

When can you not use synthetic division for dividing polynomials?

Also, the binomial must have degree 1; we cannot use synthetic division to divide by a binomial like x2 + 1. Here are the steps for dividing a polynomial by a binomial using synthetic division: Write the polynomial in descending order, adding “zero terms” if an exponent term is skipped.
