Xét \(C=16x^2+4x+100\)

\(C=4x\left(4x+1\right)+100\)

Mà \(4x\left(4x+1\right)\ge0,\forall x\)\(\forall x\)nghĩa là VỚI MỌI X nha bạn)

\(\Rightarrow4x\left(4x+1\right)+100>0,\forall x\)

\(\Leftrightarrow C>0\)

 Vậy, \(4x\left(4x+1\right)+100>0,\forall x\)(ĐPCM)

\(-25x^2+30x-100\) 

\(=-\left(25x^2-30x+100\right)\)

\(=-\left(25x^2-30x+9+91\right)\)

\(=-\left\{\left(5x-3\right)^2+91\right\}\)

\(=-\left(5x+3\right)^2-91< 0\forall x\)

  Gọi `100` số nguyên đã cho là : `a_1`;`a_2`;...;`a_(100)`

      Xét `100` tổng sau : `S_1` = `a_1`

                                      `S_2` = `a_1 + a_2`

                     ` .... `

                                      `S_(100)` = ` a_1 + a_2 + ... + a_(100) `

` => ` Ta xét 2 TH sau

` + TH1` Trong 100 tổng trên `\exists` 1 tổng `\vdots` 100 `=> ` `Đpcm`

` +TH2 ` Trong 100 tổng trên `\cancel{exists}` 1 tổng nào `vdots` 100 

        Khi đó chia `100` tổng này cho `100` ta được các số dư `in` { 1;2;3;...;99}

        Vì có `100` số dư mà chỉ có `99` khả năng dư nên theo nguyên lí Đi-rích-lê sẽ tồn tại ít nhau 2 số dư bằng nhau khi chia cho `100`

        Giả sư `a_m` và `a_n` là 2 số đó ( giả sử : `a_m > a_n` )

Suy ra ` a_m - a_n \vdots 100 ` hay ` (a_1 + a_2 + ... + a_m) -  (a_1 + a_2 + ... + a_n) \vdots 100 ` `=> ` ` a_(n+1) + a_(n+2) + ... + a_m \vdots 100 ` ` => đpcm `
