<span>List the given statements, and then list the conclusion to be proved. Now you have a beginning and an end to the proof.
Mark the figure according to what you can deduce about it from the information given. This is the step of the proof in which you actually find out how the proof is to be made, and whether or not you are able to prove what is asked. Congruent sides, angles, etc. should all be marked so that you can see for yourself what must be written in the proof to convince the reader that you are right in your conclusion.
<span>Write the steps down carefully, without skipping even the simplest one. Some of the first steps are often the given statements (but not always), and the last step is the conclusion that you set out to prove. A sample proof looks like this:</span></span>

Which is the product?
Luda [366]

Question:

Iliana multiplied 3p – 7 and 2p^2 – 3p – 4. Her work is shown in the table.

Which is the product?

6p^3 + 23p^2 + 9p + 28

6p^3 – 23p^2 – 9p + 28

6p^3 – 23p^2 + 9p + 28

6p^3 + 23p^2 – 9p + 28

Answer:

Option C: 6 p^{3}-23 p^{2}+9 p+28 is the correct answer.

Explanation:

The two expressions are 3 p-7 and \left2 p^{2}-3 p-4\right

The product of the expression can be determined by multiplying each of the first term with the second term of the expression, we get,

(3 p-7)\left(2 p^{2}-3 p-4\right)

3 p \cdot 2 p^{2}+3 p(-3 p)+3 p(-4)+(-7) \cdot 2 p^{2}+(-7)(-3 p)+(-7)(-4)

Simplifying we have,

6p^3-9p^2-12p-14p^2+21p+28

Adding the like terms, we have,

6 p^{3}-23 p^{2}+9 p+28

Thus, the product of the two expression is 6 p^{3}-23 p^{2}+9 p+28

Hence, Option C is the correct answer.
