Factoring Expressions and GCF

This video tutorial by Mumu Math and Science covers the process of factoring algebraic expressions, suitable for middle and high school students. It introduces a unique sled method for factoring, demonstrates examples with positive and negative coefficients, and emphasizes finding the greatest common factor. The video concludes with a reminder to subscribe for daily math and science content.

What is the first step in the sled method for factoring expressions?

• Write the numbers in a sled

• Add the numbers

• Find the greatest common factor

• Multiply the numbers

In the expression 48C + 72, what is the greatest common factor?

• 12

• 6

• 48

• 24

After finding the greatest common factor, what is the next step in factoring 48C + 72?

• Add the numbers

• Write the numbers inside the parentheses

• Subtract the numbers

• Divide the numbers

What is the greatest common factor of 72 and 18J?

• 6

• 3

• 18

• 9

In the expression 72 + 18J, what is the final factored form?

• 9(8 + 2J)

• 18(4 + J)

• 9(4 + J)

• 18(4 + 1J)

When factoring -12 and +8, why is it important to handle the negative sign?

• To avoid errors in addition

• To simplify the expression

• To ensure the correct sign in the factored form

• To make the numbers positive

What is the greatest common factor of -15M and -20?

• -5

• 5

• 15

• -15

In the expression -15M - 20, what is the final factored form?

• 5(3M + 4)

• -5(3M - 4)

• 5(-3M - 4)

• -5(3M + 4)

What is a key consideration when factoring expressions with negative coefficients?

• Factor out the negative sign first

• Add the negative sign later

• Ignore the negative sign

• Multiply by a positive number

What should you do after factoring an expression to ensure accuracy?

• Subtract the numbers again

• Check your work by multiplying back

• Add the numbers again

• Divide the numbers again
