Question

4a²+12ab+9b²-8a-12b. Factor this equation

Answer 1

Hey!!!!

Good Afternoon

____________


Let's arrange these first

=> 4a² + 12ab + 9b² - (8a + 12b)

Here (2a + 3b) = 4a² + 12ab + 9b²
and
(8a + 12b) = 4(2a + 3b)

=> (2a + 3b)² - 4(2a + 3b)

=> (2a + 3b)(2a + 3b - 4) <<<<< Answer

Answer 2

Answer:

(2a + 3b)(2a + 3b - 4)

Step-by-step explanation:

=> 4a² + 12ab + 9b² - (8a + 12b)

Here (2a + 3b) = 4a² + 12ab + 9b²

and

(8a + 12b) = 4(2a + 3b)  

=> (2a + 3b)² - 4(2a + 3b)

=> (2a + 3b)(2a + 3b - 4)
