Math Problem Statement

factorise

factorise

Solution

The expression in the image is:

x3+x22x+2-x^3 + x^2 - 2x + 2

Let's factorize this polynomial step by step.

Step 1: Check for common factors

There are no common factors among all terms.

Step 2: Factor by grouping

Group the terms:

(x3+x2)(2x2)(-x^3 + x^2) - (2x - 2)

Now, factor each group:

x2(x+1)2(x1)x^2(-x + 1) - 2(x - 1)

Step 3: Factor the common binomial

Notice that (x+1)(-x + 1) is the same as (x1)(x - 1), so we rewrite:

x2(1x)2(x1)x^2(1 - x) - 2(x - 1)

Now, factor out the common binomial (x1)(x - 1):

(x1)(x22)(x - 1)(-x^2 - 2)

Step 4: Simplify the remaining factor

(x1)(x22)(x - 1)(-x^2 - 2)

This is the factorized form of the given expression.
