Question

What should be added to the following expression to make perfect square a^4+a^2+1

Answer 1

Step-by-step explanation:

a⁴+a²+1=0 [acc to zero of polynomial]

if, x+1= a⁴+a²+1

p(-1)= (-1)⁴+1²+1

p(-1)=0

so, a⁴+a²+a²+1

a²(a²+1)+1(a²+1)

(a²+1)(a²+1)= {[a+b]²=a²+2ab+b²]

.

. . (a²+1)²= Answer
