Answer:

2 ± i

Step-by-step explanation:

by 5, I assume you mean +5

x² - 4x + 5 = 0

x = (-b±(√(b²-4ac)) / 2a

x = (4 ± (√(16 - 20)) / 2

x = (4 ± (√(-4)) / 2

√-4 = √4√-1 which is 2i

x = (4 ± 2i) / 2

x = 2 ± i

(01.06 LC) Which number is not in scientific notation?

Angelina_Jolie [31]

Answer:

$0.95*10^8$

Step-by-step explanation:

Hello!

Rules for scientific notation format:

Has to be multiplied to a power of 10
One factor has to be greater than 1 but less than 10

$\bold{0.95*10^8}$

There is a multiplication to a power of 10, but the other factor is less than 1.

This is NOT in Scientific Notation.

All the other options have a multiplication operation to a power of 10, and all the other factors are above 1 and less than 10.
