You can first take out an x^2 from each number , 3x^6 - 39x^4 + 108x^2 = x^2 ( 3x^4 - 39x^2 + 108) Then just factor and solve for the zero's of the equation
I think is you just need to multiply that input number just to get the right answers
Example: 5 multiply by 5 equal 25

Answer:
Each length of the rope will be 0.8 feet long
Answer:
dy/dx = 9x²+2
dy = (9x²+2) dx
dy/dt = (9x²+2) dx/dt
if x = 2 and dx/dt=5 then
dy/dt = (9*2²+2)*5 = 38*5 = 190
Replace the x values in the equation, then solve:
[(-2)^2+4]/[(-2)^2-2(-2)-48=
(4+4)/4+4-48=
8/8-48=
8/-40=
-1/5
