Q. Add.\newlineThe numerator should be expanded and simplified. The denominator should be either expanded or factored.\newline17x27x+67x2+14x= \frac{1}{7 x^{2}-7 x}+\frac{6}{7 x^{2}+14 x}=
  1. Identify common denominator: Identify the common denominator for the two fractions.\newlineThe denominators are 7x27x7x^2 - 7x and 7x2+14x7x^2 + 14x. To combine the fractions, we need a common denominator. We can factor out a 7x7x from both denominators to simplify the process.\newline7x27x=7x(x1)7x^2 - 7x = 7x(x - 1)\newline7x2+14x=7x(x+2)7x^2 + 14x = 7x(x + 2)\newlineThe common denominator will be 7x(x1)(x+2)7x(x - 1)(x + 2).
  2. Rewrite fractions with common denominator: Rewrite each fraction with the common denominator.\newlineWe need to adjust each fraction so that they both have the common denominator of 7x(x1)(x+2)7x(x - 1)(x + 2).\newlineFor the first fraction:\newline17x27x=17x(x1)=x+27x(x1)(x+2)\frac{1}{7x^2 - 7x} = \frac{1}{7x(x - 1)} = \frac{x + 2}{7x(x - 1)(x + 2)}\newlineFor the second fraction:\newline67x2+14x=67x(x+2)=x17x(x1)(x+2)\frac{6}{7x^2 + 14x} = \frac{6}{7x(x + 2)} = \frac{x - 1}{7x(x - 1)(x + 2)}
  3. Add fractions with common denominator: Add the two fractions with the common denominator.\newlineNow that both fractions have the same denominator, we can add the numerators:\newline(x+2)/(7x(x1)(x+2))+(x1)/(7x(x1)(x+2))(x + 2)/(7x(x - 1)(x + 2)) + (x - 1)/(7x(x - 1)(x + 2))\newline= (x+2+x1)/(7x(x1)(x+2))(x + 2 + x - 1)/(7x(x - 1)(x + 2))
  4. Simplify numerator: Simplify the numerator.\newlineCombine like terms in the numerator:\newline(x+2+x1)=2x+1(x + 2 + x - 1) = 2x + 1\newlineSo the combined fraction is:\newline2x+17x(x1)(x+2)\frac{2x + 1}{7x(x - 1)(x + 2)}
  5. Check for further simplification: Check for any further simplification.\newlineThe numerator 2x+12x + 1 and the denominator 7x(x1)(x+2)7x(x - 1)(x + 2) do not have any common factors, so the fraction is already in its simplest form.
