Mathematics Questions

Which statements are true regarding the fully simplified product of (b – 2c)(-3b + c)? Select two options. 1. The simplified product has 2 terms. 2. The simplified product has 4 terms. 3. The simplified product has a degree of 2. 4. The simplified product has a degree of 4. 5. The simplified product, in standard form, has exactly 2 negative terms.

Short Answer

The simplified product of the expression ((b-2c)(-3b+c)) has a degree of 2 and contains exactly 2 negative terms. The final result, after applying the distributive property and combining like terms, is (-3b^2 + 7bc – 2c^2).

Step-by-Step Solution

The correct options are: C) The simplified product has a degree of 2. E) The simplified product, in standard form, has exactly 2 negative terms.

Step 1: Expand the Expression

To begin simplifying the expression ((b-2c)(-3b+c)), we apply the distributive property (also known as the FOIL method for binomials). This involves multiplying each term in the first binomial by each term in the second binomial. The multiplication process includes:

  • Multiply (b) by (-3b) to yield (-3b^2).
  • Multiply (b) by (c) to yield (bc).
  • Multiply (-2c) by (-3b) to yield (6bc).
  • Multiply (-2c) by (c) to yield (-2c^2).

Step 2: Combine Like Terms

Next, we combine the results of our previous multiplication to simplify the expression further. The result will involve gathering terms that have the same degree. This includes:

  • From (-3b^2), we have one distinct term.
  • From (bc + 6bc), we can combine these to get (7bc).
  • Lastly, (-2c^2) remains as is since it has no like terms.

Step 3: Analyze the Resulting Expression

After combining like terms, the simplified expression is (-3b^2 + 7bc – 2c^2). Analyze the final result to determine key characteristics:

  • The highest degree of the resulting polynomial is (2), confirming that it has a degree of (2).
  • There are a total of three terms in the expression, with two of them (-3b^2) and (-2c^2) being negative.

Thus, the expressions confirm the correct options as C and E.
