Question

Factor 0.04m2 - n2.



(0.2n - m)(0.2n + m)
(0.2m - n)(0.2m - n) *****
(0.2m - n)(0.2m + n)
I think it is the one with *****************

Answer 1

help me @jim_thompson5910

Answer 2

that's not correct

Answer 3

okay how do u to it

Answer 4

think of 0.04m^2 - n^2 as (0.2m)^2 - n^2

this is a difference of squares

Answer 5

so you would use the difference of squares factoring formula

a^2 - b^2 = (a - b)(a + b)

Answer 6

so witch one is in my answer

Answer 7

@Shannon20150 ,

to factor this: 0.04m^(2)-n^(2)

okaii first, since the binomial can be factored using the difference of squares formula. This is because both terms are perfect squares. The difference of squares formula is a^(2)-b^(2)=(a-b)(a+b).

Answer 8

okay
