$P= \sqrt{1-x+(1-x)\sqrt{1-x^{2}} }+\sqrt{1-x-(1-x)\sqrt{1-x^{2}} }  $. Tính $P(\frac{-1}{2012})$
ghĩa là ko hiểu đề, mà e giải thích đơn giản hơn đi ==" –  Confusion 29-07-16 10:45 PM
:v èo cái đó gọi là hàm số đó thay x= -1/2012 –  ๖ۣۜJinღ๖ۣۜKaido 29-07-16 10:25 PM

bình phương ra mak
$P^2=2.|x|.|1-x|+2-2x$ thay $x=\frac{-1}{2012}$ vào 
$\Rightarrow P=\sqrt{\frac{4052169}{2024072}}$ 
đúng click "V" chấp nhận đúng –  ๖ۣۜJinღ๖ۣۜKaido 29-07-16 12:33 PM
