Question

(4y^a - 6x^b)(4y^a + 6x^b)

Answer 1

this is in the form (a+b)(a-b) can you see that?


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

so substitute the terms for a and b then do the 'squaring' then simplify

Answer 2

so 2a-2b ??

Answer 3

^2 means 'squared'

Answer 4

I may have confused oyu by using a & b

my equation is a 'general form.

look at YOUR equation and work out wht the equivalent of a & b are in my equaiton

Answer 5

(m+n)(m-n) = m^2 - n^2

That avoids the confusion with the a & b in your equation

So look at the FORM of your equation, and find an equivalent to m & n
