Question

Tính (x+1)^6 - (x-1)^5

Answer 1

x = -(4588317*i+3200791)/1328958;x = -(90533664*i+6936034)/79337861;x = -(1219217340*i+16944863)/4153876473;x = (1219217340*i-16944863)/4153876473;x = (90533664*i-6936034)/79337861;x = (4588317*i-3200791)/1328958;

Answer 2

má ơi để con làm má ạ =))

Answer 3

nhớ tick con nhé má :))

Answer 4

mà con làm má có hỉu ko đó

Answer 5

\(\Leftrightarrow x^6+5x^5+20x^4+10x^3+25x^2+x+2=0\)

\(\Rightarrow x^6+5x^5+20x^4+10x^3+25x^2+x=2\)

\(\Rightarrow x^6+5x^5+20x^4+10x^3+25x^2+x=x\left(x^5+5x^4+20x^3+10x^2+25x+1\right)\)

\(\Rightarrow x^5+5x^4+20^3+10x^2+25x+1=0\)

\(\Rightarrow x=\approx-0,0406065278848625\) và \(x=0\)
