<s>[INST] Solving $2x^4+x^3-11x^2+x+2 = 0$ I am having no idea how I can solve this problem.
I need help!
Here's the problem
$2x^4+x^3-11x^2+x+2 = 0$
I am learning Quadratic Expressions and this is what I need to solve, and I can't understand how :C
 [/INST] $2x^4+x^3-11x^2+x+2=0$
Note that the coefficients: $2,1,-11,1,2$ are symmetrical.
$2(x^4+1)+(x^3+x)-11x^2=0$
$2(x^4+4x^3+6x^2+4x+1)-7(x^3+x)-23x^2=0$
$2(x^4+4x^3+6x^2+4x+1)-7(x^3+2x^2+x)-9x^2=0$
$2(x+1)^4-7(x+1)^2x-9x^2=0$
$2\left(\frac{(x+1)^2}{x}\right)^2-7\left(\frac{(x+1)^2}{x}\right)-9=0$
