Best ResponseYou've already chosen the best response.0expand the left side and then get the right hand side equal to zero so you get x^2  2x  48 = 0 the trick is to get two numbers that are multiples of 48 but when added together are equal to 2 if you take 6 and 8 you get 48 so now just figure the signs you want them to equal 2 when added so pick 8 and 6 then you factor and get (x  8) (x + 6) = 0 and indeed if you FOIL you will get x^2  2x + 48
