Expand and Simplify: (x+2)(x+3)(x−3)

(x+2)(x+3)(x−3)(x²+ 3x + 2x + 6)(x - 3) : Step 1 is to expand the first two brackets. (x²+ 5x + 6)(x - 3) : Step two is to simplify the quadratic. x³-3x²+5x²-15x+6x-18 : Then expand the quadratic with the final bracket.x³+2x²-9x-18 : Final step is to simplify the expression by collecting like terms.
