Answer:

-84 + 10i

Step-by-step explanation:

first, you want to take out the negative symbol from the square root, and we know that i = sqrt(-1) (sqrt = square root)

so the equation would look like

i x sqrt(100) - 84

solve for the square root of 100 which is 10

now the equation is

10i - 84

that is the answer and you can flip the equations so it can look like the actual answer

-84 + 10i

x = -4

and we're done already!
