Understanding the Problem

When dealing with algebraic expressions, simplification is a crucial step to make the expression more manageable and easier to work with. In this problem, we are given the expression $\left(4 w^3 + 10 w^2\right) \div 2 w^2$ and we need to simplify it. Simplifying an expression involves reducing it to its simplest form by combining like terms, canceling out common factors, and performing any other necessary operations.

Breaking Down the Expression

To simplify the given expression, we need to start by breaking it down into smaller parts. We can begin by identifying the terms that are being added together inside the parentheses: $4 w^3$ and $10 w^2$ . These two terms are being added together, and then the result is being divided by $2 w^2$ . Dividing by a term is equivalent to multiplying by its reciprocal, so we can rewrite the expression as $\left(4 w^3 + 10 w^2\right) \times \frac{1}{2 w^2}$ .

Simplifying the Expression

Now that we have broken down the expression, we can start simplifying it. We can begin by multiplying the terms inside the parentheses by the reciprocal of $2 w^2$ . This gives us $\frac{4 w^3 + 10 w^2}{2 w^2}$ . To simplify this expression, we need to combine the terms in the numerator. We can do this by factoring out the common term $w^2$ from both terms. This gives us $\frac{w^2(4 w + 10)}{2 w^2}$ .

Canceling Out Common Factors

Now that we have factored out the common term $w^2$ from the numerator, we can cancel it out with the $w^2$ term in the denominator. This gives us $\frac{4 w + 10}{2}$ . Canceling out common factors is an important step in simplifying expressions, as it helps to reduce the complexity of the expression and make it easier to work with.

Final Simplified Expression

The final simplified expression is $\frac{4 w + 10}{2}$ . This expression cannot be simplified further, as there are no common factors that can be canceled out. The final simplified expression is the simplest form of the original expression, and it is the result of combining like terms, canceling out common factors, and performing any other necessary operations.

Conclusion

In this problem, we simplified the expression $\left(4 w^3 + 10 w^2\right) \div 2 w^2$ by breaking it down into smaller parts, combining like terms, canceling out common factors, and performing any other necessary operations. The final simplified expression is $\frac{4 w + 10}{2}$ . Simplifying expressions is an important step in algebra, as it helps to make the expression more manageable and easier to work with.
