Rearranging Formulae Where Subject Appears Twice

The video tutorial explains how to change the subject in equations, especially when the subject appears twice. It emphasizes using opposites, performing operations on both sides, and factorizing when necessary. The tutorial includes examples with variables M and B, guiding viewers through the process step-by-step. Viewers are encouraged to practice and engage with the content.

What is the first step when changing the subject in a formula where the subject appears twice?

• Ignore the repeated subject

• Multiply both sides by zero

• Add a constant to both sides

• Use opposites and perform operations on both sides

In the example provided, what is the initial action taken to change the subject?

• Factorize the entire equation

• Move the term least connected to the subject

• Divide by the subject

• Add a new variable

When the subject appears twice, what mathematical process is typically required?

• Integration

• Differentiation

• Factorization

• Simplification

What should you do if a variable is on a different level in the equation?

• Multiply both sides to bring it to the same level

• Subtract it from both sides

• Ignore it

• Divide it by itself

What is the final step in changing the subject when it appears twice?

• Subtract the subject from both sides

• Add a constant to both sides

• Divide by the factorized term

• Multiply by the subject
