Well, darling, the difference between x-3 and 3-x is simply the order of subtraction. In x-3, you're subtracting 3 from x, while in 3-x, you're subtracting x from 3. It's like deciding whether you want to take away $3 from your $10 bill or subtract your $10 bill from $3 – either way, you're left with a mess in your wallet.
The difference between the expressions x-3 and 3-x lies in the order of subtraction. In the expression x-3, you are subtracting 3 from x, which means you start with x and then subtract 3. In the expression 3-x, you are subtracting x from 3, which means you start with 3 and then subtract x. Therefore, the expressions represent different mathematical operations and may yield different results depending on the value of x.

That's either the sum or difference of two cubes.
(x3 + 4x2 - 3x - 12)/(x2 - 3) = x + 4(multiply x2 - 3 by x, and subtract the product from the dividend)1. x(x2 - 3) = x3 - 3x = x3 + 0x2 - 3x2. (x3 + 4x2 - 3x - 12) - (x3 + 0x2 - 3x) = x3 + 4x2 - 3x - 12 - x3 + 3x = 4x2 - 12(multiply x2 - 3 by 4, and subtract the product from 4x2 - 12)1. 4x(x - 3) = 4x2 - 12 = 4x2 - 122. (4x2 - 12) - (4x2 - 12) = 4x2 - 12 - 4x2 + 12 = 0(remainder)
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
x3 = x times x times x 3x = x plus x plus x
2x3 - 7 + 5x - x3 + 3x - x3 = 8x - 7

That's either the sum or difference of two cubes.
It means that the variable of interest appears as a power in the expression. So, for example, 3x is exponential but x3 is merely cubic. The distinction depends on the position of x.
(x3 + 4x2 - 3x - 12)/(x2 - 3) = x + 4(multiply x2 - 3 by x, and subtract the product from the dividend)1. x(x2 - 3) = x3 - 3x = x3 + 0x2 - 3x2. (x3 + 4x2 - 3x - 12) - (x3 + 0x2 - 3x) = x3 + 4x2 - 3x - 12 - x3 + 3x = 4x2 - 12(multiply x2 - 3 by 4, and subtract the product from 4x2 - 12)1. 4x(x - 3) = 4x2 - 12 = 4x2 - 122. (4x2 - 12) - (4x2 - 12) = 4x2 - 12 - 4x2 + 12 = 0(remainder)
3 - 3x + x2 - x3 = (1 - x)(x2 + 3)
x3 + x2 - 3x - 3 x(x2 + x - 3) - 3
3 ln(x) = ln(3x)ln(x3) = ln(3x)x3 = 3xx2 = 3x = sqrt(3)x = 1.732 (rounded)
