Answer 2

Given,

x² - 4x + 44x

To find,

Factors of the given problem.

Solution,

We can easily factorise x² - 4x + 44x by following the steps given below.

Now,

We have, x² - 4x + 44x

The first step will be to solve it.

So, it will become:

x² + 40x ( 4x has been subtracted from 44x.)

Now, let's factorise it.

x² + 40x

x ( x + 40) [ Taking x to be common from x² and 40x.]

Hence, the factors of the given problem will be x ( x + 40).
