# For the polynomial f (x) = x5+ 2x3+9x2-12x-30, use synthetic division to find f (-2).

Using synthetic division to find f(-2) is done in this way:

First write the coefficients of all the values of x in the expression that you are dividing starting from the largest power at the left and moving to the lower power as you move to the right. The -2 is written outside.

Now take down the 1. Multiply it by -2, and write it below the next coefficient. Add the two numbers. Again multiply the sum by -2 and move towards the right.

The steps explained above have been implemented below.

-2 | 1 0 2 9 -12 -30

| -2 4 -12 6 12

-------------------------------

=> 1 -2 6 -3 -6 -18

Once we are done, we get the coefficient of the terms that make up the quotient and the remainder.

**The required quotient is x^4 - 2x^3 + 6x^2 - 3x - 6. **

**And the remainder is -18.**
