Answer:
I don;t know what the question is but I know that z is an imaginary number.
Step-by-step explanation:
z=-302+19.3i
that means that it doesn't represent an actual number but is imaginary.
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.
Take the number with the variable on one side and the numbers alone on the otherside of the equal sign but don't forget to change the negative and positive sign
less .... means subtract
than .... means switch the order
product .... means multiply
5 x -4 - 8

Step-by-step explanation:
Im so sorry.. I did not mean to submit an answer..
And I honestly don't know how to get rid of my answer.. but I will try to help.
4x²- 20x=0 =
= -√5,
= √5
3x²-42=0 =
= -√14,
= √14
2x²-14x=0 =
= 0,
= 7
8x²-98=0 =
= -
