The will be (3x - 2) x (3x + 2) x (9x2 + 4)
I'm not exactly sure but I think it might be but if you were to do 4(x-7) that would be 15 because fifteen minutes seven equals eight and eight time four is thirty two Hope this helps!
You’d have to solve your equations!
they’d be the same when x=-56
and when x=-56 they’d BOTH equal -27
Similarities: same atomic number
Differences: they have a different number of neutrons
