Answer:
B. x=1+2i or x=1-2i.
Step-by-step explanation:
The equation is given as;
x²-2x+5=0
complete the square method to find value of x as;
x²-2x = -5
x²-2x + 1 = -5 + 1
x²-2x +1 =-4
( x-1 )² = -4
x-1 = ±√-4 ---------<em>where √-1 = i</em>
x-1 =± 2i
So;
x-1 = + 2i
x= 1+2i
or
x= 1-2i
x= 1-2i
You are correct. The answer is C, 11 units
The ordered pairs are (3,6) and (14,6)
The x numbers are the same. The y numbers are different.
So, you would subtract 3 from 14 (14-3) to get the answer of 11 units.
Hope this helps you! (:
