Question

Which of the following is a solution of x2 + 4x + 6?

−2 + i times the square root of 2
2 + i times the square root of 2
−2 + three i times the square root of 2
2 + three i times the square root of 2

Answer 1

Nevermind, I gave up and guessed on about 12 questions just now

Answer 2

you have this quadratic equation-> \(\large x^2+4x+6\)

to find the roots just apply the quadratic formula
quadratic formula-> \(\large x= \Large \frac{-b \pm \sqrt{b^2-4ac}}{2a}\)
here \(a\) --> coefficient of \(x^2\) term
\(b\) --> coefficient of \(x\) term
\(c\)-->constant term

Answer 3

There is a certain amount of math requiered, but I agree that \(i\)maginary numbers are not the world's most necessary stuff.
