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.
