\[(2\pm 2\sqrt{2}i)/3\]
how'd you get that..?
solving the equation... :D
nice haha but im still confused on what to do after the x's are on the bottom part of the fractions
make the bottom part x^2 u will get like this: (1-x)/x^2=3/4 after cross multiplication, u can get a quadratic expression, solve that u will get the answer :)
ok so i got to the (1-x)/x^2=3/4 what do i do next? O.o
cross multiplication..
agree with dalvoron. Crossed multiply it and get x-x^2=3/4. then transpose 3/4 to the other side:)
am i supposed to get \[1\pm \sqrt{2}i/2\]?
No need for complex numbers here.\[\frac{1}{x^2}-\frac{1}{x}=\frac{3}{4}\]\[\Leftrightarrow \frac{4}{x^2}-\frac{4}{x}=3\]\[\Leftrightarrow 4-4x=3x^2\]
thanks! i just use the quadratic formula and then get both answers :D
Quite right, quite right. Regular factorising is possible also. What did you get as your solutions for x?
Correct, good job!
i have a few more problem that i cant get -.-
