Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it's essential to understand the steps involved in simplifying complex expressions. In this article, we will focus on simplifying the expression 7y2y2−9×4y+1214y3\frac{7 y^2}{y^2-9} \times \frac{4 y+12}{14 y^3}. We will break down the expression into smaller parts, simplify each part, and then combine them to get the final simplified expression.

Understanding the Expression

The given expression is a product of two fractions: 7y2y2−9\frac{7 y^2}{y^2-9} and 4y+1214y3\frac{4 y+12}{14 y^3}. To simplify this expression, we need to first simplify each fraction individually and then multiply them together.

Simplifying the First Fraction

The first fraction is 7y2y2−9\frac{7 y^2}{y^2-9}. We can simplify this fraction by factoring the denominator. The denominator y2−9y^2-9 can be factored as (y+3)(y−3)(y+3)(y-3). Therefore, the first fraction can be written as 7y2(y+3)(y−3)\frac{7 y^2}{(y+3)(y-3)}.

Simplifying the Second Fraction

The second fraction is 4y+1214y3\frac{4 y+12}{14 y^3}. We can simplify this fraction by factoring the numerator and the denominator. The numerator 4y+124 y+12 can be factored as 4(y+3)4(y+3), and the denominator 14y314 y^3 can be factored as 2×7×y32 \times 7 \times y^3. Therefore, the second fraction can be written as 4(y+3)2×7×y3\frac{4(y+3)}{2 \times 7 \times y^3}.

Multiplying the Fractions

Now that we have simplified each fraction, we can multiply them together to get the final expression. When multiplying fractions, we multiply the numerators together and the denominators together. Therefore, the product of the two fractions is:

7y2(y+3)(y−3)×4(y+3)2×7×y3=7y2×4(y+3)(y+3)(y−3)×2×7×y3\frac{7 y^2}{(y+3)(y-3)} \times \frac{4(y+3)}{2 \times 7 \times y^3} = \frac{7 y^2 \times 4(y+3)}{(y+3)(y-3) \times 2 \times 7 \times y^3}

Canceling Common Factors

Now that we have multiplied the fractions, we can simplify the expression by canceling common factors. The expression has several common factors that can be canceled out. The (y+3)(y+3) terms in the numerator and the denominator can be canceled out, as well as the 77 terms in the numerator and the denominator. Therefore, the expression simplifies to:

7y2×4(y+3)(y+3)(y−3)×2×7×y3=4y2(y−3)×2×y3\frac{7 y^2 \times 4(y+3)}{(y+3)(y-3) \times 2 \times 7 \times y^3} = \frac{4 y^2}{(y-3) \times 2 \times y^3}

Final Simplification

The expression can be further simplified by canceling out the common factor of y2y^2 in the numerator and the denominator. Therefore, the final simplified expression is:

4y2(y−3)×2×y3=2(y−3)×y\frac{4 y^2}{(y-3) \times 2 \times y^3} = \frac{2}{(y-3) \times y}

Conclusion

In this article, we simplified the expression 7y2y2−9×4y+1214y3\frac{7 y^2}{y^2-9} \times \frac{4 y+12}{14 y^3} by breaking it down into smaller parts, simplifying each part, and then combining them to get the final simplified expression. We used factoring, canceling common factors, and simplifying to arrive at the final answer. This process demonstrates the importance of simplifying algebraic expressions and the steps involved in simplifying complex expressions.
