Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?

X=1 = i√19        Put a vertical line through the second = sign

Step-by-step explanation:

when writing this put a line under all the + signs 0k and / is divided by 2

2 + √4-4(1)(20)

2 + √4-80 /2

x=2 +√76/2

x=2 +2i√19    the twos cancel out

1 +i√19

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

i think the answer is c sorry if it's wrong
