Answer: 4a^4 - 11a^3 + 25a^2 - 13a - 5
Explanation:
Check out the attached image below for the box method diagram. It's basically a 3 by 3 box showing all the 9 terms, some of which combine together (only the like terms though).
Each inner box or inner cell is the result of multiplying the outer terms. For example, in row 2, column 2 we have the outer terms -3a and -2a multiply to get 6a^2. Figure 1 shows the full table filled out while figure 2 has that same table highlighted with different colors to show the like terms.
The like terms are:
-15a and 2a, which combine to -13a
20a^2, 6a^2 and -a^2 which combine to 25a^2
-8a^3 and -3a^3 which combine to -11a^3
Those results are added to the other terms but we do not combine them (as they are not like terms). That's how we end up with the final answer. This is a quartic polynomial as the degree (largest exponent) is 4. There are five terms in this polynomial when fully simplified.

Answer:
y = 2
y = 6
Step-by-step explanation:
The first thing to do is to find the turning point of the function. For this, derive and equal zero to expression
=
x = 0 and x = -2
We have 2 inflection points.
Then we have 2 tangent lines:
At the point (0, 2)
Since it is a point of inflection, then the slope of this line is 0. Therefore the tangent line is:
y = 2.
At the point (-2, 6).
The slope of this line is 0.
The equation of the tangent line to the function is:
y = 6
