x/(.900-2x)^2 = 4 How do I solve for x?
:
Assume the problem is:
= 4
FOIL
= 4
:
= 4
:
x = 4(4x^2 - 3.6x + .81)
:
x = 16x^2 - 14.4x + 3.24
:
0 = 16x^2 - 14.4x - x + 3.24
:
16x^2 - 15.4x + 3.24 = 0
:
Solve this using the quadratic formula
Two solutions: x~.652 and x~.311
;
Check both of these in the original equation
