Question

x⁴+x²+1=0 please answer the question using factorization method ​

Answer 1

Answer:

x4+x2+1=0

It can be written as

(x2+1)2−x2=0

(x2−x+1)(x2+x+1)=0

In above step I used (a2−b2)=(a−b)(a+b)

Now

(x2−x+1)=0 & (x2+x+1)=0

Now we have two quadratic equations. We can use the quadratic formula.
