\(\left(x+\dfrac{1}{5}\right)^2+\dfrac{17}{25}=\dfrac{26}{25}\)
\(\Leftrightarrow\left(x+\dfrac{1}{5}\right)^2=\dfrac{9}{25}\)
=>x+1/5=3/5 hoặc x+1/5=-3/5
=>x=2/5 hoặc x=-4/5
\(\left(x+\dfrac{1}{5}\right)^2+\dfrac{17}{25}=\dfrac{26}{25}\)
\(\Leftrightarrow\left(x+\dfrac{1}{5}\right)^2=\dfrac{9}{25}\)
=>x+1/5=3/5 hoặc x+1/5=-3/5
=>x=2/5 hoặc x=-4/5
(x + 1/5)^2 + 17/25=26/25
\(\left(x+\dfrac{1}{5}\right)^2+\dfrac{17}{25}=\dfrac{26}{25}\)
28) (x+1/5)2 + 17/25=26/25
(x+1/5)2+17/25=26/25
28) (x+1/5)2 + 17/25=26/25
35) x+2/ 327+ x+3/326+x+4/325+x+5/324+x+349/5=0
tìm x
(x+1/5)^2+17/35=26/25
(x+1/5)2 + 17/25 = 26/25
x = ????
ai giúp mình với làm bt đến đây thì tắc kt giúp mình nhé
