How do i factorise 5w-25-xw+5?

Question

I do not have a clue how to factorise if the equation is not a quadratic?!!

Answer 1

Probably a typo in the problem statement .
Or else it would read 5w - 20 - xw ;
Should be : 5w - 25 - xw + 5x
You could factorise something even if it were not quadratic , like :
5w - 25 - xw + 5x = w (5 - x) - 5 ( 5 - x) = (w - 5)(5 - x)
I suppose a "x" was dropped in the last term .

Answer 2

First, let's do the easy bit: -25 + 5 = -20. So now we have:

5w - xw -20. This can be further simplified to: w(5 - x) -20.

Somebody has put this in the form of an equation w(5 - x) = 20. Whilst this is perfectly correct, if you are asked to factorise something, it's normally considered correct to leave it in it's original form.

Answer 3

First, look for common factors between 2 of the terms, and rearrange the question.
Then you take out the common factors for each pair.

In your question, I believe that you must have made a typo.

5w-25-xw+5
= 5w-xw-20 (cannot be factorised as there aren't any common terms between the 3 of the terms.)

Answer 4

Assuming 5w-25-xw+5=0

combine like terms

5w-20-xw=0

then rearrange

5w-xw-20=0

then factorise

w(5-x)-20=0

which can be rewritten as:

w(5-x)=20

Answer 5

To factorise is to take out common factors.
In this the common factor is 5
5(w-5 -xw+1)

Answer 6

The only thing you can do is simplify by combining like terms. 5w - xw - 20.

Answer 7

The expression does not seem to be factorised.

Answer 8

divide through by 5
so you get
5(w-5-xw/5+1)
