Understanding the Problem

When simplifying algebraic expressions, it's essential to combine like terms to make the expression more manageable and easier to work with. In this problem, we're given the expression (3m45)+(2m42)\left(3 m^4-5\right)+\left(2 m^4-2\right) and asked to simplify it.

What are Like Terms?

Like terms are terms that have the same variable raised to the same power. In other words, they have the same base and exponent. For example, 2m42m^4 and 3m43m^4 are like terms because they both have the variable mm raised to the power of 4.

Combining Like Terms

To combine like terms, we add or subtract their coefficients. The coefficient is the number that multiplies the variable. For example, in the term 2m42m^4, the coefficient is 2.

Simplifying the Expression

Let's simplify the given expression by combining like terms:

(3m45)+(2m42)\left(3 m^4-5\right)+\left(2 m^4-2\right)

We can start by combining the like terms with the variable m4m^4. The coefficients of these terms are 3 and 2, respectively. We add these coefficients together:

3m4+2m4=5m43m^4 + 2m^4 = 5m^4

Now, we can rewrite the expression with the combined like terms:

5m4525m^4 - 5 - 2

Next, we can combine the constant terms by adding their coefficients:

52=7-5 - 2 = -7

So, the simplified expression is:

5m475m^4 - 7

Checking the Answer Choices

Let's compare our simplified expression with the answer choices:

A. 3m463 m^4-6 B. 3m463 m^4-6

Our simplified expression is 5m475m^4 - 7, which is not among the answer choices. However, we can see that the answer choices are incorrect because they don't match our simplified expression.

Conclusion

In this problem, we simplified the expression (3m45)+(2m42)\left(3 m^4-5\right)+\left(2 m^4-2\right) by combining like terms. We added the coefficients of the like terms with the variable m4m^4 and combined the constant terms. Our simplified expression is 5m475m^4 - 7, which is not among the answer choices.
