X^2+7x-30
what we do is we find what 2 number multiply to get -30 and add to get 7
factor 30
30=2 times 3 times 5
we know that is has to be negative eventually so one is negative and one is positivie so we do2 factors and add
2 times 5=10
10 and -3
add
10-3=7
checks
10 times -3=-30
so we put those in
(x-3)(x+10)
factored
