Q. Subtract.\newlineThe numerator should be expanded and simplified. The denominator should be either expanded or factored.\newline8xx2+8x+166x2+4x= \frac{8 x}{x^{2}+8 x+16}-\frac{6}{x^{2}+4 x}=
  1. Identify denominators: First, let's identify the denominators in the given expression. We have two fractions with different denominators: x2+8x+16x^2 + 8x + 16 and x2+4xx^2 + 4x. To subtract these fractions, we need a common denominator.
  2. Factor denominators: The denominator x2+8x+16x^2 + 8x + 16 is a perfect square trinomial, which factors to (x+4)2(x + 4)^2. The denominator x2+4xx^2 + 4x can be factored by taking out the common factor xx, resulting in x(x+4)x(x + 4).
  3. Find common denominator: Now, we need to find a common denominator for the two fractions. The least common denominator (LCD) is x(x+4)(x+4)x(x + 4)(x + 4), which is the same as x(x+4)2x(x + 4)^2.
  4. Rewrite fractions: Next, we will rewrite each fraction with the common denominator. The first fraction already has the denominator x + \(4)^22\, so we only need to adjust the second fraction by multiplying the numerator and denominator by x + \(4)\ to have the common denominator.
  5. Subtract fractions: After adjusting the second fraction, we have: (8x(x+4)26(x+4)x(x+4)2)(\frac{8x}{(x + 4)^2} - \frac{6 \cdot (x + 4)}{x(x + 4)^2})
  6. Expand numerator: Now, we can subtract the fractions since they have the same denominator: \newlineegin{equation}\newline\frac{88x - 66 \times (x + 44)}{x(x + 44)^22}\newline(\newline\)egin{equation}
  7. Simplify expression: We expand the numerator to simplify the expression: 8x6x24=2x248x - 6x - 24 = 2x - 24
  8. Factor numerator: The simplified form of the expression is: \newlineegin{equation}\newline\frac{22x - 2424}{x(x + 44)^22}\newline\end{equation}
  9. Final result: Finally, we check if the numerator can be factored further. Since 22 is a common factor of both terms in the numerator, we can factor it out:\newline2(x12)x(x+4)2\frac{2(x - 12)}{x(x + 4)^2}
