Question 370780
simplify the following equations using the distributive property? 

1. -2b(5a - 5b) + 4(-3ab - 4b to 2nd power)
---
= -10ab+10b^2 -12ab - 16b^2
---
= -6b^2 - 22ab
--------------------------------------- 


2. 6(a - 3b) + 2(-b - 4a)
---
= 6a-18b-2b-8a
---
= -2a-20b
--------------------------------------- 


3. 2a -{6b - 3[a -(b _ 3a)]}
---
= 2a -{6b-3[a-b+3a]
---
= 2a -{6b-12a+b]
---
= 2a-7b+12a
---
= 14a-7b
