Or use: 4+2 = 6 (coefficient of x) 4*2 = 8 (constant at the end)

Rule is: the numbers you are looking for have sum 6 and product 8

ah thanks so it is 4 and 2 because 4 + 2 = 6 and 4 x 2 = 8

Yes! 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...

E.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 ;)
