Question 104040
the factors of 7 are 7 and 1 ... these have to be combined with factors of 8 to get -10
since the 8 is positive and the 10 is negative, the factors have to be negative


factors of 8:  +-1,8 ... +-2,4


this is NOT factorable


IF the 8 were negative; the factors would be (7x+4)(x-2)
