Find x value in quartic equation
Not what you're looking for?
To solve the quartic equation, one of the approaches is to seek squares on both sides. For example, to find x, in ax^4+bx^2+cx=d. One way is to convert the equation to the following format: (square root of a x^2+e)^2=(gx+h)^2. However, when a, e, g and b becomes irrational number, it is difficult to apply this strategy. Here, I provide a common solution for this type of equation with a specific example.

solve x^4 + 10x = 5x^2 + 5.
First, x^4-5^2+10x-5=0. (I)
we factor the left side: (x^2+bx+c)(x^2+dx+e)=0. (II)
x^4+(d+b)x^3+(c+e)x^2+(be+cd)x+ce=0.
when we compare equation (I) and ...
