\n" ); document.write( "\n" ); document.write( "\"sqrt%282%2At+%2B+3%29+%2B+2+=+sqrt%28t+-2%29\".....IF WE ARE DEALING WITH REAL NUMBERS,
\n" ); document.write( "this prolem has no solution..reason is as follows ...we have square root of (t-2) on the r.h.s.for it to be real or meaning full,t should be equal to 2 or more than 2,since then only t-2 can have a square root.but if t>=2,then on the l.h.s.we have 2t+3 which will be definitely more than t-2,on the r.h.s.so
\n" ); document.write( "sqrt.of (2t+3)on l.h.s.will be more than sq.rt.of (t-2) on the r.h.s.then obviously we cant get the r.h.s. by adding 2 to the l.h.s.
\n" ); document.write( "IF YOU ARE DOING COMPLEX NUMBERS PLEASE TELL ME...TO GIVE YOU THE METHOD OF ATTACK FOR THAT
\n" ); document.write( "OR LET ME MODIFY THE PROBLEM TO GIVE YOU THE METHOD OF SOLUTION
\n" ); document.write( "\"sqrt%282%2At+%2B+3%29+-+2+=+sqrt%28t+-2%29\".....
\n" ); document.write( "\"sqrt%282%2At+%2B+3%29+-+sqrt%28t+-2%29=+2\".....
\n" ); document.write( "square both sides,we get
\n" ); document.write( "2t+3+t-2+2*sq.rt.{(2t+3)*(t-2)}=4
\n" ); document.write( "3t+1-4=2sq.rt(2t^2-4t+3t-6)
\n" ); document.write( "3t-3=2sq.rt(2t^2-t-6).....square both sides again
\n" ); document.write( "(3t-3)^2=4*(2t^2-t-6)
\n" ); document.write( "9t^2+9-2*3*3*t=8t^2-4t-24
\n" ); document.write( "9t^2+9-18t-8t^2+4t+24=0
\n" ); document.write( "t^2-14t+33=0
\n" ); document.write( "t^2-11t-3t+33=0
\n" ); document.write( "t(t-11)-3(t-11)=0
\n" ); document.write( "(t-3)(t-11)=0
\n" ); document.write( "hence t=3 or 11....since we squared the given eqn.twice it is a good practice to back check the answers to ensure that we have not introduced any additional roots by squaring.
\n" ); document.write( "so putting t=3 in original eqn. we get
\n" ); document.write( "\"sqrt%282%2A3+%2B+3%29+-+2+=+sqrt%283+-2%29\".....or...3-2=1....correct
\n" ); document.write( "so putting t=11 in original eqn. we get
\n" ); document.write( "\"sqrt%282%2A11+%2B+3%29+-+2+=+sqrt%2811+-2%29\".....or.....5-2=3...correct
\n" ); document.write( "
\n" );
