Simplify the expression:

\[ 5a + 2a(5 - b) \]

Please, I need help.

Asked by crishart

Answer (2)

5a + 2a(5 + (-b)) = 5a + 2a(5 - b)
Use the distributive property which states a(b+c) = ab + ac
5a + 10a - 2ab
Simplify like terms
15a - 2ab

The expression 5 a + 2 a ( 5 − b ) simplifies to 15 a − 2 ab by using the distributive property and combining like terms. This involves expanding the term 2 a ( 5 − b ) first and then consolidating the results. Overall, the final simplified expression is 15 a − 2 ab .
