Answer 1

@518nad could you help me with this one pleaseeee?:)

Answer 2

imaginary roots occur when you try to take the squareroot of a negative number

Answer 3

ok so how would I find it?

Answer 4

Answer 5

you solve for x and see which one involves taking a squareroot of negative number

Answer 6

there could also be complex roots, meaning roots with an imaginary and real part in the form a+ib

Answer 7

im not sure if when they say imaginary roots they are including the imaginary parts in complex roots, in that case ud have to solve the longer quadratic equations too, you can use the quadratic formula and see which one of those also have an imaginary part

Answer 8

So it would be the first and second one at the bottom? ok thank you! youre such a big help!

Answer 9

yup, not too sure though, just check with someone, if they are including complex roots as an imginary root

Answer 10

I'd suggest you simply label your result with "imaginary root" or "complex root."

Note that the imaginary quantity 5i could be re-written as a complex root:" 0 + 5i.

Answer 11

an imaginary root can be written as a 'complex' root but a complex root cannot be written as an imaginary one

Answer 12

Completely agreed.
