find a value to complete the expression x^2 + ?x +30 so that it can be factored into the product of two binomials.how can i find the value?

There are many possible answers. Here are some with integers.
x^2 + 11x + 30 = (x+6)(x+5)
x^2  11x + 30 = (x6)(x5)
x^2  17x + 30 = (x15)(x2)
x^2 + 17x + 30 = (x+15)(x+2)
x^2  31x + 30 = (x1)(x30)
