Best ResponseYou've already chosen the best response.0nice haha but im still confused on what to do after the x's are on the bottom part of the fractions

Best ResponseYou've already chosen the best response.0make the bottom part x^2 u will get like this: (1x)/x^2=3/4 after cross multiplication, u can get a quadratic expression, solve that u will get the answer :)

Best ResponseYou've already chosen the best response.0ok so i got to the (1x)/x^2=3/4 what do i do next? O.o

Best ResponseYou've already chosen the best response.1\[x^{2}x^{1}=(3/4)\]\[\Leftrightarrow\frac{1}{x^2}\frac{1}{x}=\frac{3}{4}\]

Best ResponseYou've already chosen the best response.0agree with dalvoron. Crossed multiply it and get xx^2=3/4. then transpose 3/4 to the other side:)

Best ResponseYou've already chosen the best response.0am i supposed to get \[1\pm \sqrt{2}i/2\]?

Best ResponseYou've already chosen the best response.1No need for complex numbers here.\[\frac{1}{x^2}\frac{1}{x}=\frac{3}{4}\]\[\Leftrightarrow \frac{4}{x^2}\frac{4}{x}=3\]\[\Leftrightarrow 44x=3x^2\]

Best ResponseYou've already chosen the best response.1Quite right, quite right. Regular factorising is possible also. What did you get as your solutions for x?
