Answer:
From what it looks like AC and CB are equal so first,
6^2 x 6^2 = AB
then,
6 x 6 = 36
36 x 36 = 1296
Finally, find the square root of that number.
the answer should be 6cm... WOW, that was so confusing but it should be 6cm.
If the roots are 3, 2 and -3 then the function is created by multiplying
(x-3) * (x-2) * (x+3)
x^2 -5x +6 * (x+3)
x^3 -5x^2 +6x + 3x^2 -15x +18 = 0
x^3 -2x^2 -9x +18 = 0
The first three are the ones
