Answer: y = x^2 + 6x+ 9 = 0. (X+3)^2= 0 when x=3. This has one root.

X^2-2x -24 = 0 a= 1 b=-1 and c= -24 x = {-(-1) +/- sqrt((-1)^2 -4 x 1 x (-24)}/2

X = [1 +/- sqrt(97)]/2

Alik [6]

Answer:

begin{aligned}

   & x = \frac{D_x}{D} = \frac{-616}{-154} =  4 \\

   & y = \frac{D_y}{D} = \frac{ 616}{-154} = -4 \\

   & z = \frac{D_z}{D} = \frac{-770}{-154} =  5

         \end{aligned}begin{aligned}    & x = \frac{D_x}{D} = \frac{-616}{-154} =  4 \\    & y = \frac{D_y}{D} = \frac{ 616}{-154} = -4 \\    & z = \frac{D_z}{D} = \frac{-770}{-154} =  5          \end{aligned}
