@gudda1122 : yea ye walla hogya 😃 bt thnx
@gudda1122 , @Brooklyn , @JS-M and others online ... I got another interesting mail...from one of the newbie...
"sampras bhai, I am unable to solve the whole set in 2 hrs... though I know how to solve the qns... can you suggest any trick"
I replied " bhai ..yehi toh rona hai sabka... qns sabhi ko aate hain, aisa kam hi hota hai ki CGL ka koi qn kisii ko na aaye ... chances are there for only 4-5 qns...or in the present trend max upto 10 taking account of wrong qns put by SSC, still hardly anybody can solve all 90 qns...all that we need to practice to increase speed... myself too struggling with speed as i donn practice much... or donn have time to do that... ATB"
@Brooklyn said:dont do nythng simply do square, den x^3= x^2*x
yr i did it like thz.........
(2x-1)^2 = 3
4(x^2-x) = 2
x(x-1) = 1/2
x = 1/2, 3/2
for x = 1/2........value z 4
for x = 3/2.........value z 26.5.................ab ye 10 kaha se aaya..
@JS-M said:yr x ki kya value li hai??
yaar main bas simply
2x=rt3+1
ab yahan se mujhe pata tha long division method use karna hai
so main 1 ko x ki taraf le gaya so that koi bhi value irrational nahi aaye
and then square kar diya
(2x-1)^2=(rt3)^2
@Brooklyn said: @sampras @sampras : mera to 1 tym hoke hi "bas hogya....nt intrested in goin again walla" mood ban gya hai
kaun se AFSB mein gaye the No.2 or else...
@JS-M : bhai itna complexq karo lyf ko
simply let it n square
x^2= [ 2+rt(3) ]/ 2
x^3= x^2 *x = [5 +3rt(3)] / 4
ab values put karo 10 aayega
@Brooklyn said: @JS-M : bhai itna complexq karo lyf kosimply let it n squarex^2= [ 2+rt(3) ]/ 2x^3= x^2 *x = [5 +3rt(3)] / 4ab values put karo 10 aayega
bhai is mein yeh hi trick hai
if we will put value then question bada ho jayega
use long division method

bhai square kar ke polynomial nikal lo usse given expn mein divide kardo straightway will get remainder 10
@sampras : Yar acc to me logic pta hai kya hona chahiye....for xam....d o dose q dat can be done under 1 min coz all can be done bt doin dose which are least tym consuming is d trick

sahi jawab...........

No2 I found very co-operative... at the end of conference the GTOs themselves came to me.. and inspired me to try again...

to yaar iske baad kya kiya x = 1/2 hi to aa raha hai nd ans 4...
tumhara 10 kaise aaya....explainnnnnnnnn

bhaiya its subjective issue some will have command on profit loss, CI SI and Time- work... which are not my cakes... I prefer doin algebra, numbers , trigo, geo etc... first
@sampras : mere to solid walla katta hogya!! i frp discussion my grp members didnt conclude coz 2 faught...so whole grp diqualified. 1st day hi behj diya :/

yea to each's own :)

given : x=(rt3+1)/2 ...... 2x-1 = rt3 ..... squaring... 2x^2-2x-1 = 0
now given eqn ... 4x^3+2x^2-8x+7 = (2x^2-2x-1)(2x+3) + 10 = 10 ..... Ans

PPDT nahi hua tha kya ... donn know wats the pattern nowadays... it used to be earlier 2 screening tests... psychological test followed by PPDT
