# Suppose

Suppose you know that the length of a line segment is 15, x2=6, y2=14 and x1= -3. Find the possible value of y1. Is there more than one possible answer? Why or why not?

Correct result:

y11 =  26
y12 =  2

#### Solution:

Our quadratic equation calculator calculates it.

${y}_{12}={q}_{2}=2$

we make circle k with centre S(x2,y2) and radius r = 15 . Then we make vertical line x= -3 . It make two intersections with circle k thus solutions are two: y11,y12.
