Answer 2

To simplify the expression (x+2)(x²-2x+4)-x(x-3)(x+3), we can start by expanding each part and then combining like terms.

Expanding the first part: (x+2)(x²-2x+4) = x(x²-2x+4) + 2(x²-2x+4) = x³-2x²+4x + 2x²-4x+8 = x³+8

Expanding the second part: -x(x-3)(x+3) = -x(x²+3x-3x-9) = -x(x²-9) = -x³+9x

Now we can substitute these results back into the original expression and simplify further: (x+2)(x²-2x+4)-x(x-3)(x+3) = (x³+8) - (-x³+9x) = x³+8 + x³-9x = 2x³ - 9x + 8

So, the simplified form of the expression (x+2)(x²-2x+4)-x(x-3)(x+3) is 2x³ - 9x + 8.
