This is like using a sledgehammer to kill an ant.
Turn the equation to quadratic from the second line by simple substitution.

[@RamasamyArumugam1927]

Thank you for the clear explanation

[@ullikrishna4997]

PUT X^2=t

[@ivoelsam]

What this counting for?

[@Rabauke_KDF]

2

[@laxmankhanal6389]

2 or _2

[@uwenordmann198]

The solution is very inconvenient

[@ranbirdas5786]

we can take x^2 = y and solve the resulting quadratic equation, which I find very Convienient...

[@dardoburgos3179]

+2 y -2.

[@NgoziNgozi799]

Seems😅very complicated to me I need a math tutor

[@user-fh2pj3uu6k]

X=2

[@madebymarco99]

Didn't understand how i^2 = (-1). Am I missing anything?

[@Learnn_with_me.]

Root if negative 1 is i means iota

[@vikramreddyvaranasi5363]

totally confusing🙃🙃🙃🙃
