Ok, I'm assuming you're solving for the zero's? Which is basically the x-intercepts (Places where the graph crosses the x axis.
First, I graphed the line 3x^4+5x^3-10x^2-20x-8
and it crosses over the x axis at 4 spots: x=-1,-2,-2/3,2
so that means when we factor out the quadratic, we should have something like:
(3x+2)(x+1)(x-2)(x+2)
so when you foil all that out, you should get the original equation.
I used desmos graphing calculator (google it) and wolframalpha to help factor.
Good luck!

Arlecino [84]

Answer:

The length of Ave's garden is 8 feet.

Step-by-step explanation:

The area of a rectangle can be calculated by:

              A = l × w

Where; A represents the area, l the length and w, width.

Thus from the question,

          32 =  l × 4

           l = 32 /4

           l = 8

Therefore, the length of the garden required is 8 feet.
