2h²-3h-18 doesn't factor in rational numbers.
x²-9x-36 = (x - 12) (x + 3)
64p²-63p+16 doesn't factor in real or rational numbers.
15a²b+5a²-10a
Factor out the common factor:
5a (3ab + a - 2)
What remains in parentheses doesn't factor any farther.
a²-11ab+18b² = (a - 9b) (a - 2b)
18-9r+r² = (r - 6) (r - 3)
