Question

factorize x^7 + x^6 + x^5 + x⁴​

Answer 1

Answer is x square pls mark as brainliest

Answer 2

^3 +x^2 +x +1 =0

=> x^2(x+1) + 1(x+1)=0

=> (x+1)(x^2 +1)=0, Therefore ,

Either x+1=0 or x^2+1=0, if x+1=0 => x=-1

If x^2 +1=0 => x^2 = -1 , x^2 = i^2 =>x= √(i^2)

x=±i , then the required solution

x= -1 , +i , -i
