(2xsquare)

Answer 1

what is the question?

Answer 2

Wanting to know how to work the problem

Answer 3

there is no question

Answer 4

all you have done is given an expression, what do you want done with it

Answer 5

factorise?

Answer 6

if you look at 2x^2 -4x
to facotrise this, you want to take what is common

just by looking at it, you notice that 4 is in the 2 times table
so you know that 2 goes into 4, meaning you can take out a factor of 2

since 2x2=4

taking out a factor of 2 would give

2(x^2 - 2x)
but you can also see that x^2 is x times x and -2x is -2 times x
which means they both have x in common, so we take x out as a factor too!

2x(x-2)
then you do the same for the xy-2y

you can see that this has a y in common, so take y out as a factor

y(x-2)

now you just add these together

2x(x-2)+y(x-2)

from here, you can notice that they both have (x-2) in common, so if you take (x-2) out as a factor you get

(x-2)(2x+y)

Answer 7

Thank you so much that is what I was looking for
