Answer:
- 5(9c +2d)
- -6(x -9)
- 5(6a +7b)
Step-by-step explanation:
The idea here is to put the greatest common factor outside parentheses using the distributive property. The terms have different variables, so the factor of interest will only be a number. Your knowledge of multiplication tables helps with this.
1. = 5(9c +2d)
2. = -6(x -9) . . . . or 6(-x +9)
3. = 5(6a +7b)
