Step-by-step explanation:
The answer is: [B]: " -10a + 6b² − 4b + 3 " .
_____________________________________
Explanation:
____________________
Given:
____________________________
-2(5a − 3b²) − 4b + 3 ;
_________________________________
"Use the distributive property [of multiplication] to expand the expression."
______________________________________________
Note the distributive property of multiplication:
______________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
______________________________________________
So, we have: " -2(5a − 3b²) − 4b + 3 " ;
______________________________________________
Start with: " -2(5a − 3b²) " ;
______________________________________________
-2(5a − 3b²) = (-2*5a) − (-2*3b²) = (-10a) − (-6b²)
= -10a + 6b²
________________________________________________
→ Now, bring down the rest of the problem;
________________________________________________
-10a + 6b² − 4b + 3 ; which is: Answer choice: [B].
