Q. Subtract.The numerator should be expanded and simplified. The denominator should be either expanded or factored.x2+8x+168x−x2+4x6=
Identify denominators: First, let's identify the denominators in the given expression. We have two fractions with different denominators: x2+8x+16 and x2+4x. To subtract these fractions, we need a common denominator.
Factor denominators: The denominator x2+8x+16 is a perfect square trinomial, which factors to (x+4)2. The denominator x2+4x can be factored by taking out the common factor x, resulting in x(x+4).
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), which is the same as x(x+4)2.
Rewrite fractions: Next, we will rewrite each fraction with the common denominator. The first fraction already has the denominator x + \(4)^2\, so we only need to adjust the second fraction by multiplying the numerator and denominator by x + \(4)\ to have the common denominator.
Subtract fractions: After adjusting the second fraction, we have: ((x+4)28x−x(x+4)26⋅(x+4))
Expand numerator: Now, we can subtract the fractions since they have the same denominator: egin{equation}\frac{8x - 6 \times (x + 4)}{x(x + 4)^2}(\newline\)egin{equation}
Simplify expression: We expand the numerator to simplify the expression: 8x−6x−24=2x−24
Factor numerator: The simplified form of the expression is: egin{equation}\frac{2x - 24}{x(x + 4)^2}\end{equation}
Final result: Finally, we check if the numerator can be factored further. Since 2 is a common factor of both terms in the numerator, we can factor it out:x(x+4)22(x−12)
