Answer 2

Answer:

do you do 2 - 46 - 7 equals 20 do x 2 - 4 academy you have to factorise middle 1 is - 4 x so what you have to do it you have to you have to factorise stor for such an example if you take that a minus A + 9 - 3 x + 9 x minus 3 Idiots give me how much you can take ki tattoo on the one side and to on the one side so that what you have to do it factorise that to on the website then you have to factorise after factorising both will be come as equal written a sequel and other equation left of this will be answer
