HELP Solve x2 – 5x – 24 = 0 by completing the square.
Question 16 options: A) x = 3 and x = –8
B) x = 6 and x = –4
C) x = –6 and x = –4
D) x = –3 and x = 8

step-by-step explanation:

bob the banana

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
