Answer:
6a² + 4ab² - 19a - 6b² + 15
Step-by-step explanation:
(3a + 2b² - 5 )( 2a - 3 )
In this question, We need to multiply (3a + 2b² - 5 ) with ( 2a - 3 ).
We can't multiply it directly, Thus, We will divide ( 2a - 3 ) into two,
→ 2a(3a + 2b² - 5 ) - 3(3a + 2b² - 5 )
→ 6a² + 4ab² - 10a - 9a - 6b² + 15
→ 6a² + 4ab² - 19a - 6b² + 15
We can't further simplify.
∴ (3a + 2b² - 5 )( 2a - 3 ) = 6a² + 4ab² - 19a - 6b² + 15.
