Simplify by adding two rational terms

The video tutorial explains how to add two rational terms by first reviewing the process of adding fractions with common denominators. It then extends this concept to rational terms involving binomials, demonstrating how to find a common denominator by multiplying the denominators. The tutorial concludes with simplifying the expression by combining like terms.

What are the two rational terms that need to be added in the problem?

• 6/(b+8) and 4/(b+6)

• 6/(b-8) and 4/(b-6)

• 6/(b-6) and 4/(b-8)

• 6/(b+6) and 4/(b+8)

What is the least common multiple of 3 and 4 when adding 1/3 and 1/4?

• 15

• 12

• 9

• 6

What is the common denominator used for the rational terms 6/(b-6) and 4/(b-8)?

• (b+6)*(b-8)

• (b-6)*(b+8)

• (b+6)*(b+8)

• (b-6)*(b-8)

What is the result of combining the like terms 6B and 4B?

• 8B

• 10B

• 12B

• 14B

What is the simplified form of the expression after combining like terms and simplifying?

• 10B - 72 / (b+6)*(b-8)

• 10B - 72 / (b-8)*(b-6)

• 10B - 72 / (b-6)*(b+8)

• 10B - 72 / (b+8)*(b+6)
