Best ResponseYou've already chosen the best response.2now this time we need all combinations of 18 1 x 18 = 18 2 x 9 = 18 6 x 3 = 18 so out of all the combinations, which 2 numbers will give me 11 (the numbers are on the left side of the equation)

Best ResponseYou've already chosen the best response.0Find the two factors of 18 that when added together equal 11: 9x2=18 and 9+2=11, so the two factors are 9 and 2. (x9) and (x2) set the two equations to 0 and solve: x=9 and x=2.

Best ResponseYou've already chosen the best response.2wow that's good (x9)(x2) = x^22x9x+18 = x^211x+18
