Giải thích các bước giải:
`x^3+x^2-11x+10=0`
`=>(x^3-2x^2)+(3x^2-6x)-(5x-10)=0`
`=>(x-2)(x^2+3x-5)=0`
`=>(x-2)[(x^2+3x+9/4)-29/4]=0`
`=>(x-2)[(x+3/2)^2-29/4)=0`
`=>(x-2)(x+3/2-sqrt29/2)(x+3/2+sqrt29/2)=0`
`=>`\(\left[ \begin{array}{l}x=2\\x=\dfrac{\sqrt{29}-3}2\\x=\dfrac{-\sqrt{29}-3}2\end{array} \right.\)
