halp!!!!

(2h+9)/(h^2+9h) = (1/20)


how do i go about this?!

[qwertysaur]

Cross multiply to get

(20)(2h+9)=h^2+9h

40h+180=h^2+9h

Standard form

h^2 - 31h - 180 = 0

(h - 36)(h + 5) = 0

h = 36 and h = -5

EDIT: qwerty beat me to it.

One note: I had to use the quadratic formula to figure out how to split the equation.

Here's a tip:

to type out h², just type


h<</>sup>2<</>/sup>


:</>D!
