Question 1103122: Solve: x^4 � 10x + 9 = 0

The equation you show clearly has a root at x=1. The other roots are one irrational and a pair of complex roots.

I'm wondering, though, if the equation was supposed to be x^4-10x^2+9=0. That equation is easy to solve.

The solutions are -3, 3, -1, and 1.
