Question

x^4=25

Answer 1

We need to subtract 25 on both sides giving us
\[x^4-25=0\]
Now notice the left hand side is a difference of squares so it can be factored!

Answer 2

\[(x^2-5)(x^2+5)=0\]

Answer 3

Set both factors equal to 0
and solve both equations for x
You will get two real solutions and 2 imaginary solutions
