Question
I. (2x-3)3+ 1/((2x-3)³)=2 II.
4y²+(y+8)^2= 157 In the following questions two equations numbered I and II are given. You have to solve both the equations. Give answer if;Solution
let 2x-3=a (2x-3)3+ 1/((2x-3)³)=2 a³+ 1/(a³ )=2 a6+ 1=2a³ a6- 2a³+1=0 (a3- 1)2= 0 a³=1 a=1 2x-3=1 2x=4 x=2 4y²+(y+8)2= 157 4y²+y²+64+16y=157 5y²+16y-93=0 5y2-15y+31y-93=0 5y(y-3)+31(y+3)= 0 5y(y-3)+31(y- 3)= 0 y=3,-31/5 Hence, no relationship cannot be established between x and y.
