Synthetic division can be used for polynomials with real or complex coefficients and for polynomials whose degree is greater than 1. The method is also sometimes called long division of polynomials. The goal of synthetic division is to simplify the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Division\">division<\/a> process and to avoid having to factor the polynomial. The method is based on the fact that if x \u2212 a is a factor of a polynomial P(x), then P(a) = 0.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"To_divide_a_polynomial_Px_by_x_%E2%88%92_a_synthetic_division_can_used_The_steps_for_synthetic_division_are_as_follows\"><\/span>To divide a polynomial P(x) by x \u2212 a, synthetic division can used. The steps for synthetic division are as follows:<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>1. Write the polynomial P(x) in standard form, with the term of highest degree first.<\/p>\n<p>2. Write the number a underneath the leading coefficient of P(x).<\/p>\n<p>3. Draw a line under the terms of P(x).<\/p>\n<p>4. Multiply each term of P(x) by a, and write the result underneath the term.<\/p>\n<p>5. Add the terms in the lower row, and write the result underneath the line. This sum is P(a).<\/p>\n<p>6. If P(a) = 0, then x \u2212 a is a factor of P(x). Otherwise, x \u2212 a is not a factor of P(x).<\/p>\n<h4><span class=\"ez-toc-section\" id=\"For_example_to_divide_x34x2-5x-6_by_x2_synthetic_division_can_used_The_steps_are_as_follows\"><\/span>For example, to divide x^3+4x^2-5x-6 by x+2, synthetic division can used.

Multiply each term of the polynomial by 2, and write the result underneath the term: 2x^3+8x^2-10x-12.<\/p>\n<p>5. Add the terms in the lower row, and write the result underneath the line: 2x^3+8x^2-10x-12.
