144/12 which is 12 so x=12
Your answer should be A, sorry if that’s incorrect it just makes the most sense! :)
the answer to the problem y=−15x3+18x2
I think you mean GCF, or greatest common factor, in which case, yes, this is always true. An odd number has no factors of 2 or multiples of 2, so there is no way a factor of an odd number can be divisible by 2. Even if the even number has no odd factors, That would simply mean they have no common factors greater than 1, so the GFC would just be 1.
Answer:
16x^2 -36 does factorise
x^2 -6x +36 don't factorise
x^2 -4x +4 does factorise as (x−2)(x−2)
36x^2 +108x +819 does factorise as (2x+3)(2x+3)
25x^2 +30x +36 don't factorise
Hope this helps!
