Introduction

In algebra, division of polynomials is a crucial operation that helps us simplify complex expressions and solve equations. When dividing a polynomial by another, we aim to find the quotient and remainder. In this article, we will focus on dividing the expression $$2y^2 + 8$$ by $$2y + 4$$ and determine which expression represents the quotient and remainder.

The Division Process

To divide $$2y^2 + 8$$ by $$2y + 4$$, we will use long division, a method that involves dividing the highest degree term of the dividend by the highest degree term of the divisor. The process involves several steps:

Divide the leading term of the dividend ($$2y^2$$) by the leading term of the divisor ($$2y$$).
Multiply the entire divisor by the result from step 1 and subtract the product from the dividend.
Bring down the next term of the dividend and repeat the process until we have no more terms to bring down.

Step 1: Divide the Leading Term

We start by dividing the leading term of the dividend ($$2y^2$$) by the leading term of the divisor ($$2y$$). This gives us $$y$$.

Step 2: Multiply and Subtract

Next, we multiply the entire divisor ($$2y + 4$$) by the result from step 1 ($$y$$). This gives us $$2y^2 + 4y$$. We then subtract this product from the dividend ($$2y^2 + 8$$). This leaves us with a remainder of $$4y + 8$$.

Step 3: Bring Down the Next Term

Since we have no more terms to bring down, we can stop here. The remainder is $$4y + 8$$.

Step 4: Write the Quotient and Remainder

The quotient is the result from step 1, which is $$y$$. The remainder is $$4y + 8$$.

Expressing the Quotient and Remainder

We can express the quotient and remainder as a single expression. We can write the quotient as $$y$$ and the remainder as $$4y + 8$$. However, we can also express the remainder as a fraction with the divisor as the denominator. This gives us $$\frac{4y + 8}{2y + 4}$$.

Simplifying the Remainder

We can simplify the remainder by factoring out the greatest common factor (GCF) of the numerator and denominator. The GCF of $$4y + 8$$ and $$2y + 4$$ is 4. Factoring out 4 gives us $$\frac{4(y + 2)}{2(y + 2)}$$.

Canceling Common Factors

We can cancel out the common factors in the numerator and denominator. The common factor is $$(y + 2)$$. Canceling this factor gives us $$\frac{4}{2}$$.

Simplifying the Fraction

We can simplify the fraction by dividing the numerator and denominator by their greatest common factor (GCF). The GCF of 4 and 2 is 2. Dividing both the numerator and denominator by 2 gives us $$\frac{2}{1}$$, which simplifies to 2.

Writing the Final Expression

We can now write the final expression for the quotient and remainder. The quotient is $$y$$ and the remainder is $$2$$.

Conclusion

In conclusion, when dividing $$2y^2 + 8$$ by $$2y + 4$$, the quotient is $$y$$ and the remainder is $$2$$. This can be expressed as the expression $$y - 2 + \frac{16}{2y + 4}$$.

Final Answer

The final answer is: $\boxed{y - 2 + \frac{16}{2y + 4}}$
