Question

find all real solutions of the equation:
(2x^4)+(4x^2)+1=0

Answer 1

let a = x^2
so a^2 = x^4

so your equation will become something like

2a^2 + 4a + 1 = 0

now you can use quadratic formula to solve for a (because this is not factorable)

Answer 2

then whatever value you get for a, take the square root to get the value of the solutions

Answer 3

does that help?

Answer 4

Yes, that helps. Thank You.
