Find the product of all constants \(t\) such that the quadratic \(x^2 + tx - 9\) can be factored in the form \((x+a)(x+b)\), where a and b are integers.
a+b has to equal t
a*b has to equal - 9
-9 1
9 -1
3 -3
-3 3 two of these are repeats so 9 , -1 and 3, -3 these add together to make t = 8 or 0 summed = 8
