Best ResponseYou've already chosen the best response.0Hmm \[\frac{x^3 + 2xax^3+b + ax bx^2}{x^21}\]

Best ResponseYou've already chosen the best response.1all i know is tht we have fractions like this and limit goes to infinite the limit will b calculated for the monomials in the highest power

Best ResponseYou've already chosen the best response.0x^3  ax^3 = 0 => a= 1

Best ResponseYou've already chosen the best response.0\[\large \frac{\frac{x^3 + 2xax^3+b + ax bx^2}{x^2}}{\frac{x^21}{x^2}} = \frac{xax +2\frac1{x} + \frac b{x^2} + \frac {a}{x^2} b}{1  \frac{1}{x^2}}\]

Best ResponseYou've already chosen the best response.1Ishaan y u divided it by x^2???

Best ResponseYou've already chosen the best response.0\[x\to \infty\] so, if xax isn't Zero the limit would approach infinity. And xax can be Zero only when a=0.

Best ResponseYou've already chosen the best response.0Hmm it's the matter of choice angela. I felt dividing it with \(x^2\) would be easier.

Best ResponseYou've already chosen the best response.0\[\frac{xax +2\frac1{x} + \frac b{x^2} + \frac {a}{x^2} b}{1  \frac{1}{x^2}}\]With a=1\[\large \frac{x1\cdot x +2\frac1{x} + \frac b{x^2} + \frac {1}{x^2} b}{1  \frac{1}{x^2}} = \frac{2\frac1x + \frac{b}{x^2} + \frac1{x^2} b}{1\frac1{x^2}}\] \[x\to \infty \implies \frac{1}{x}\to 0\] The limit is now \(\frac{b}1\).

Best ResponseYou've already chosen the best response.1Ishaan u got a random value of a??? O.o

Best ResponseYou've already chosen the best response.0It's not a random value. \(xax\). and \(x\to \infty\). It's important form the both terms to cancel out. Which is only possible if a=1.
