Question

Help please! pretty easy i just dont remember how to do it

Answer 1

Explanation:

the disc. is the part under the root in the general formula

which is equal b^2 - 4 x a x c

in this equation a = 1 " coefficient of x^2"

b = 0 "coefficient of x which isn't found here "

c = 12 " the absolute "

`0^(2) - 4`×
`1`×
`12` = -4×12 = something i don't have a calculator

but it will be negative so the roots will be complex and unreal
