Question

Solve: 3x ^6+ x^5-27x^4+27x^2 -x-3=0​

Answer 1

Answer:

x=-1 , x=-1/3 , x=1 , x=-3 or x=−3 or x=2.6180 or x=0.38196

Step-by-step explanation:

Let's solve your equation step-by-step.

=> 3x^6+x^5−27x^4+27x^2−x−3=0

Step 1: Factor left side of equation.

=> (x+1)(3x+1)(x−1)(x+3)(x^2−3x+1)=0

Step 2: Set factors equal to 0.

=> x+1=0 or 3x+1=0 or x−1=0 or x+3=0 or x^2−3x+1=0

=> x=-1 , x=-1/3 , x=1 , x=-3 or x=−3 or x=2.6180 or x=0.38196
