To create this inequality graph, you will have an open circle at 50 and an arrow pointing to the right.
Since the bag must be over 50, we draw an open circle at fifty.
Since the fee goes towards the bags over 50, we draw an arrow pointing to the right.
Easier if you first factor out the " - " sign. Then you have:
–8x3 – 2x2 – 12x – 3 = -1(<span>8x3 + 2x2 + 12x +3).
</span>
Start with 12 + 3. This factors to 3(4x+1). Next, focus on 8x^3+2x^2. This factors to 2x^2*(4x+1). So, the binomial factor 4x+1 is common to the first two terms and the second two terms. We get: (4x+1) ( 2x^2 + 3).
Now put the "-" sign back in, and we get - (4x+1) ( 2x^2 + 3) (answer)
Please note: Use "^" to denote exponentiation. 2x2 is meaningless; it should be 2x^2.
It would be 89.
