Q. Write the coefficient of x

^{2}in the following(i) x

^{3}+ 2x^{2}+ 1 (ii) (x-2)^{2}(iii) x^{2}(iv) 2Q. Find two rational numbers in the form $\frac{p}{q}$ between 0.34344344434444........ and 0.363663666........

Please don't send any links for the answer

if $x+\frac{1}{x}+2=0$, then the value of

x^{33 }+x^{32 }+x^{13 }+x^{12 }+x+ 1 is^{1/3}
