+73 The following quadratic expression is factorable.
x^2 + bx + 19
If b is an integer, what are all the possible values of b?
______ and ______
+37146 My understanding is this what two numbers multiplied together = 19 ( prime number with only the factors 1 and 19 or -1 and -19) and ADDED together = b
Which means b = 20 (from 19 + 1) or -20 (from -19 and - 1)
