The video tutorial explains how to solve rational equations when all fractions have the same denominator. It emphasizes the importance of identifying excluded values, which make the denominator zero, and extraneous solutions that do not satisfy the original equation. Two examples are provided: the first involves solving an equation with x-3 denominators, and the second involves a quadratic equation. The tutorial demonstrates how to clear fractions, solve resulting equations, and verify solutions to ensure they satisfy the original equation.

What is the first step in solving a rational equation?

• Multiply both sides by zero

• Clear the fractions from the equation

• Add the numerators together

• Subtract the denominators

Why must we identify excluded values in rational equations?

• To avoid division by zero

• To make the equation linear

• To simplify the equation

• To find the solution faster

In the first example, what is the excluded value for x?

• x = 7

• x = -3

• x = 0

• x = 3

CCSS.HSA.REI.A.2

How do we verify that x = 7 is a solution in the first example?

• By comparing it to the extraneous solution

• By ensuring it is an excluded value

• By substituting it into the resulting equation

• By checking if it satisfies the original equation

What type of equation is solved in the second example?

• Linear equation

• Quadratic equation

• Cubic equation

• Exponential equation

What is the excluded value in the second example?

• x = 0

• x = -6

• x = 6

• x = 36

Tags

CCSS.HSA.REI.A.2

Why is x = 6 considered an extraneous solution in the second example?

• Because it satisfies the original equation

• Because it is an excluded value

• Because it is a negative value

• Because it is a solution to the resulting equation

What is the correct solution for the second example?

• x = 36

• x = -6

• x = 0

• x = 6

What is the importance of verifying solutions in rational equations?

• To find extraneous solutions

• To make the equation more complex

• To confirm the solution satisfies the original equation

• To ensure the solution is an excluded value

Tags

CCSS.HSA.REI.A.2

What is an extraneous solution?

• A solution that is an excluded value

• A solution that satisfies the original equation

• A solution that does not satisfy the original equation

• A solution that is a positive integer
