The answer is 4 squared minus 2 squared as 4 squared is 16 minus 2 squared, which is 4, gives you 12 as an answer.

That can be factored to (x - 2)(x - 1)

-22 - 12 = -8

9 minus 8

It is 2n^3 + 7n^2 - 13n + 3

so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
