Q. Add.The numerator should be expanded and simplified. The denominator should be either expanded or factored.7x2−7x1+7x2+14x6=
Identify common denominator: Identify the common denominator for the two fractions.The denominators are 7x2−7x and 7x2+14x. To combine the fractions, we need a common denominator. We can factor out a 7x from both denominators to simplify the process.7x2−7x=7x(x−1)7x2+14x=7x(x+2)The common denominator will be 7x(x−1)(x+2).
Rewrite fractions with common denominator: Rewrite each fraction with the common denominator.We need to adjust each fraction so that they both have the common denominator of 7x(x−1)(x+2).For the first fraction:7x2−7x1=7x(x−1)1=7x(x−1)(x+2)x+2For the second fraction:7x2+14x6=7x(x+2)6=7x(x−1)(x+2)x−1
Add fractions with common denominator: Add the two fractions with the common denominator.Now that both fractions have the same denominator, we can add the numerators:(x+2)/(7x(x−1)(x+2))+(x−1)/(7x(x−1)(x+2))= (x+2+x−1)/(7x(x−1)(x+2))
Simplify numerator: Simplify the numerator.Combine like terms in the numerator:(x+2+x−1)=2x+1So the combined fraction is:7x(x−1)(x+2)2x+1
Check for further simplification: Check for any further simplification.The numerator 2x+1 and the denominator 7x(x−1)(x+2) do not have any common factors, so the fraction is already in its simplest form.
