Simplifying Expressions and Factoring

Factoring is the opposite of distributing

• True

• False

Combine like terms

Simplify the following expression:
-6x + 4(-x - 3)

• -2x - 12
• 10x + 12
• -10x - 12
• -2x + 12

Simplify the following expression:

-8 (5b + 2) -7 (b - 5)

• -33b + 19

• -47b² + 21

simplify the following expression
- 3( 5a + 2 - 3c)

• 15a + 6 - 9c
• -15a - 6 - 9c
• -15a + 9c -6
• -15a - 6 + 9

Factor Completely:

35c - 15d

• 5(7c + 3d)

• 5(7d - 3c)

• 5(7c - 3d)

• -5(-7c+3d)

Is the following expression expanded correctly or incorrectly?:
