Kẻ Bz//Ax

Ta có: Ax//Bz

\(\Rightarrow\widehat{BAx}=\widehat{ABz}=30^0\)(so le trong)

\(\Rightarrow\widehat{zBC}=\widehat{ABC}-\widehat{BAx}=90^0-30^0=60^0\)

Ta có: \(\widehat{zBC}+\widehat{BCy}=60^0+120^0=180^0\)

Mà 2 góc này là 2 góc trong cùng phía

=> Bz//Cy

Mà Bz//Ax

=> Ax//Cy

\(\left(x+2\right)\left(x+3\right)\left(x+4\right)\left(x+5\right)-8=\left(x^2+7x+10\right)\left(x^2+7x+12\right)-8\)

Đặt \(x^2+7x=t\)

\(\left(t+10\right)\left(t+12\right)-8=t^2+22t+120-8\)

\(=t^2+22t+112=\left(t+8\right)\left(t+14\right)\)

Theo cách đặt \(=\left(x^2+7x+8\right)\left(x^2+7x+14\right)\)
