What is the m at that line segment?

M=(6,5)

Step-by-step explanation:

M stands for midpoint. You use the midpoint formula. The formula is (x1+x2/2) and (y1+y2/2). 3 plus 9 is 12 for x1 and if you divide that by two because of the equation, you get 6. You do the same thing for the y. Hope this helps! :)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
