### What is Synthetic Division?

Synthetic Division is an abbreviated way of dividing a polynomial by a binomial of the form (*x* + *c*) or (*x* – *c*). We can simplify the division by detaching the coefficients.

In this lesson, we will look at Synthetic Division, which is simplified form of long division.

Synthetic Division is an abbreviated way of dividing a polynomial by a binomial of the form (

**Example:**

Evaluate (*x*^{3} – 8*x* + 3) ÷ (*x* + 3) using synthetic division

**Solution:**

(*x*^{3}– 8*x* + 3) is called the dividend and (*x* + 3) is called the divisor.

**Step 1:**

Write down the constant of the divisor with the sign changed

–3

**Step 2:**

Write down the coefficients of the dividend. (Remember to add a coefficient of 0 for the missing terms)

**Step 3:**

Bring down the first coefficient.

**Step 4:**

Multiply (1)( –3) = –3 and add to the next coefficient.

Repeat Step 4 for all the coefficients

We find that (*x*^{3}– 8*x* + 3) ÷ (*x* + 3) = *x*^{2} – 3*x* + 1
