Best ResponseYou've already chosen the best response.1Or use: 4+2 = 6 (coefficient of x) 4*2 = 8 (constant at the end)

Best ResponseYou've already chosen the best response.1Yes! Another one: x²+5x+6 = (x+2)(x+3) They're not all that easy though, because sometimes there are negative numbers involved, or there seem to be many numbers to choose from...

Best ResponseYou've already chosen the best response.1E.g. this one: x²3x28 Sum = 3 (many possibilities, don't bother with them!) Prod. = 28...hmm that could be: (one of them should be negative, because product is negative ) 1, 28 or 1,28 no: sum goes wrong 2, 14 or 2, 14 no .... 4, 7 or 4, 7 ...yes! Sum of 4 and 7 is 3 So: (x7)(x+4) Now I will stop ;)
