taking x and 3 , common
x(4x^2-1)
========
3(2x+1)(2x-1)
x(2x+1)(2x-1)
==========
3(2x+1)(2x-1)
=x/3

yaa absolutely me to agre with ur ans
Ans is “D”
if u simplify the expression we will get the resultant as x/3.

ans is ![]()
4X^3-X=X(4X^2-1)
X(4X^2-1)/(2X+1)(3(2X-1))
=X/3=9999/3=3333.

D ![]()
(4x^3-x)/(2x+1)(6x-3)
=x(4x^2-1)/(2x+1)3(2x-1)
=x(2x+1)(2x-1)/3(2x+1)(2x-1)
=x/3
now,x=9999,
then,x/3=9999/3=3333=option D

4X^3-X=X(4X^2-1)
can any1 explain how they got the above term

D) 3333
4X^3-X=X(4X^2-1)=x(2x+1)(2x-1)=a
and (2x+1)(6x-3)=3(2x+1)(2x-1)=b
given…a/b=x/3

(4x^3-x)/(2x+1)(6x-3)
=x(4x^2-1)/(2x+1)3(2x-1) {taking x common outside from
numerartor n takin 3 common from the
term 6x-3, from denominator.}
=x(2x+1)(2x-1)/3(2x+1)(2x-1) {then split numerator 4x^2-1 as
(2x-1)(2x+1).}
=x/3
=9999/3 {substituting value of x(given)}
=3333
Atleast now have u understood? (for all those people, who had NOT understood the sum)
