Find all the zeros of the equation 3x^2-4=x^4

  x = (±√7 ±i)/2

Step-by-step explanation:

The equation can be rewritten to look like a quadratic in x². In standard form, it is ...

  (x²)² -3x² +4 = 0

Then by the quadratic formula, ...

  x² = (-(-3) ± √((-3)²-4(1)(4)))/(2(1)) = (3 ± √-7)/2

  x = ±√((3 ±i√7)/2)

This can be simplified to ...

  x = ±(√7)/2 ±i/2

Comment on simplification

The method I used was a combination of numerical technique and guessing. The value of x has a rational imaginary part, so we guessed that the real part was a simple square root. That guess turned out to be accurate.

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.
