Question

Need help ASAP:
Find the complex zeros of the polynomial function:
x^4+8^2+7

Answer 1

I am assuming you mean
\[\Large x^4 + 8x^2 + 7\]
In that case, you can always let \(\large u = x^2\)
So that you get \[\Large u^2 + 8u + 7=0\]
Solve for u using which method for quadratics is within your comfort zone, and tell me what you get :D
