Understanding Absolute Value Equations

The video tutorial explains how to solve absolute value equations. It begins with an introduction to the concept of absolute value, emphasizing that the absolute value always takes the positive value inside. The tutorial then demonstrates the process of isolating the absolute value bars and setting up two equations to find solutions. It provides examples of solving basic and advanced absolute value equations, highlighting the importance of considering both positive and negative scenarios. The tutorial concludes with a summary of the steps involved in solving these equations.

What is the first step in solving an absolute value equation?

• Add a constant to both sides

• Subtract a constant from both sides

• Isolate the absolute value expression

• Multiply both sides by a constant

When solving an absolute value equation, how many solutions can you typically expect?

• One

• Two

• Three

• None

In the equation |n + 8| = 14, what are the possible values for n?

• 22 and -6

• 6 and -22

• 14 and -14

• 8 and -8

What operation is performed after isolating the absolute value in a complex equation?

• Add a constant to both sides

• Multiply both sides by a constant

• Set up two separate equations

• Subtract a constant from both sides

In the equation 3|x + 5| = 15, what is the first step to solve it?

• Divide both sides by 3

• Add 5 to both sides

• Subtract 5 from both sides

• Multiply both sides by 3

What is the result of dividing both sides of the equation 3|x + 5| = 15 by 3?

• |x + 5| = 5

• |x + 5| = 0

• |x + 5| = 3

• |x + 5| = 15

After isolating the absolute value, what should you do next?

• Set up two separate equations

• Add a constant to both sides

• Multiply both sides by a constant

• Subtract a constant from both sides

In the equation |4x - 1| = 5, what are the possible values for 4x?

• 3 and -3

• 4 and -6

• 5 and -5

• 6 and -4

What is the final step in solving an absolute value equation?

• Check the solutions in the original equation

• Add a constant to both sides

• Multiply both sides by a constant

• Subtract a constant from both sides
