    You use the FOIL method to solve this. FOIL stands for First,Outside,Inside,Last and refers to the positions of the terms in the binomials. IOW, for "(x + 6)(x + 3)", you would: Multiply the (F)irst terms first: x*x = x^2 Then multiply the (O)utside terms: x*+3 = +3x Then multiply the (I)nside terms +6*x = +6x And finally you multiply the last terms: +6 * +3= +18 Now you string these products all together and you get: X^2 +3x +6x +18 Now combine common terms and you're done: X^2 +9x +18
