First: find the greatest common factor > by finding a number that's divisible by 36 and -4. We can use: 4
Second: take 4 and bring it the front and multiply it by the remaining variables:
= 4(9x^2 - y^2)
Third: factor the expression in the parenthesis: (3x - y)(3x+y) and rewrite:
= 4(3x - y)(3x+y)

1) 36 is 6^2, x^2 is x * x , 4 is 2^2 , and Y^2 is y *y
2) so (6x-2y)(6x+2y) is a simple form of 36x^2 - 4y^2
3) to make it more simple : you can multiply each part by 1/2
and you'll get 4(3x-y)(3x + y)

the way your wrote this out doesn't rather make experience... yet when for the first element you attempt to element -4y^2+12y-16 Then the answer should be -4(y-4)(y+a million) And if the 2d crew of stuff is all meant to be for the issue 42x^3y^4-63x^2y then you actually could get -21xy^3

4(3x-y)(3x+y)
take the GCF out (4) which gives you 4(9x^2-y^2)
then factor by difference of sq.
to give you 4(3x-y)(3x+y)

diff of squares:
(6x - 2y)(6x + 2y)
Can also factor out 2 from both:
4(3x - y)(3x + y)
