If using the method of completing the square to solve the quadratic equation x^2-13x+5=0, which number would have to be added to "complete the square"?

Step-by-step explanation:

Coefficient of the x term: -13

Divide it in half: -13/2

Square it: (-13/2)^2 = (13/2)^2

Use (13/2)^2 to complete the square.

(13/2)^2

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
