how do u factor this question: 2w(y-2z)-x(y-2z)
(y-2z)(2w-x)
It is (y-2z) (2w - x) this is by taking the common factor (y-2z) from both
how did u get that
by taking the common factor
They're both multiplied by the common factor
can u show me step by step, im confused on factoring equations
Here we use the distributive law in reverse
distributive law says a (b+d) = ab + ad This can also be put as ab + ad = a (b+d) Understood now??
yes thank u
but how to do u get the answer since the question has ( )
when u have more than one number i.e. it is two terms then u have to put brackets so in your case a(b) + a(d) = a (b+d)
oh ok, thanks again
Since (y-2z) is common to both treat it as a and 2w as b and -x as d
and how about x^2-2x+3x-6 how do u do that one
Here in the first two terms x^2 and -2x we have common factor x so they can be combined using distributive law as x(x -2) Now we have to resolve the last two terms so that we get (x-2) in the bracket this can be done as follows +3 (x-2)
So the question become x(x-2) +3 (x-2) We find (x-2) is common so it becomes (x-2) (x+3) Got it??
oh ok, thanks
Where r u located sanasaj???
y
just curious, I am frm Delhi, india
oh ok, im from the US
U going to school or home-study??
home-study
I think u shud buy books by R. D. Sharma - an Indian author - for maths. I think u must b in 7th or 8th standard
