I need help with factoring this polynomial please.
h^2-9hs+9s^2
-----
a = 1 ; b = -9s ; c = 9s^2
----------------------------------
Using the quadratic formula you get:
h = [9s +- sqrt(81s^2 - 4*1*9a^2)]/2
---
h = [9s +- sqrt(45s^2)]/2
h = [9s +- 3s*sqrt(5)]/2
----------
Factors:
(h-[[9s + 3s*sqrt(5)]/2])(h-[9s - 3s*sqrt(5)]/2])
