Q. Add.The numerator should be expanded and simplified. The denominator should be either expanded or factored.x+47+x+63=
Identify common denominator: Identify the common denominator for the two fractions.To add the fractions, we need a common denominator. The least common denominator (LCD) for (x+4) and (x+6) is the product of the two, since they are distinct linear factors.Common Denominator: (x+4)(x+6)
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 (x+4)(x+6).First Fraction: x+47×x+6x+6=(x+4)(x+6)7(x+6)Second Fraction: x+63×x+4x+4=(x+4)(x+6)3(x+4)
Expand numerators of fractions: Expand the numerators of both fractions.Now we expand the numerators to simplify the fractions.First Fraction's Numerator: 7(x+6)=7x+42Second Fraction's Numerator: 3(x+4)=3x+12
Combine fractions: Combine the fractions.Now that both fractions have the same denominator, we can combine them by adding their numerators.Sum: (7x+42+3x+12)/((x+4)(x+6))
Simplify numerator of combined fraction: Simplify the numerator of the combined fraction. Combine like terms in the numerator. Simplified Numerator: (7x+3x)+(42+12)=10x+54
Write final simplified fraction: Write the final simplified fraction.The combined fraction with the simplified numerator is:Final Answer: (10x+54)/((x+4)(x+6))
