<PRE><B>Question 173108</B>
how do i convert this into a form i can solve as a quadratic equation? 
9(p-300)^2= 1.02^2 *p(400-p)
---------------
expand all the terms.
9(p-300)^2= 1.02^2 *p(400-p)
9(p^2 - 600p + 90000) = 1.0404*(400p - p^2)
9p^2 - 5400 p + 810000 = 416.16p - 1.0404p^2
p^2 - 600p + 90000 = 46.24p - 0.1156p^2
Collect terms
1.1156p^2 - 646.24p + 90000 = 0
