Answer:
−1 + i times the square root of 3
is the answer.
Step-by-step explanation:
Given is a quadratic equation in x
using completion of squares method
Equate to 0
Take square root
Subtract one from both sides
x = [/tex]-1±i\sqrt{3}[/tex]
The last option namely
−1 + i times the square root of 3 only matches with our answre
Hence last option is right.
Hey there! I'll only explain you how to solve it and you'll have to find the answer yourself so you learn! <3 Anyhow, To simplify a complex fraction here are the steps.
(1) Convert mixed numbers to improper fractions.
(2) Reduce all fractions when possible.
(3) Find the least common denominator (LCD) of all fractions appearing within the complex fraction.
(4) Multiply both the numerator and the denominator of the complex fraction by the LCD.
(5) When possible reduce, simplify and convert to mixed numbers, any final fraction results.
Hope this helps! <3
