## FACTORIZATION WORKSHEET QUESTION1

In this page factorization worksheet question1 we are going to see solution of first problem.

**Step 1: **Arrange
the dividend and the divisor according to the descending powers of x
and then write the coefficients of dividend in the first zero. Insert 0
for missing terms.

**Step 2: **Find out the zero of the divisor.

**Step 3: **Put 0 for the first entry in the second row.

**Step 4: **Write
down the quotient and remainder accordingly. All the entries except the
last one in the third row constitute the coefficients of the quotient.

**Question 1**

Factorize each of the following polynomial x³ - 2 x² - 5 x + 6

**Solution**

Let p (x) = x³ - 2 x² - 5 x + 6

x = 1

p (1) = 1³ - 2 (1)² - 5 (1) + 6

= 1 - 2 - 5 + 6

= 7 - 7

= 0

So we can decide (x - 1) is a factor. To find other two factors we have to use synthetic division.

So the factors are (x - 1) and (x² - x - 6). By factoring this quadratic equation we get (x - 3) (x + 2)

Therefore the required three factors are (x - 1) (x - 3) (x + 2)
