Answer:

(2x + 6)(-2x)

Step-by-step explanation:

-4x² - 12x

-4x² - 12x= - (4x² + 12x)

-4x² - 12x= - (4x² + 12x)= - {(2x)² + 2•2x•3 + 3² - 3²}

-4x² - 12x= - (4x² + 12x)= - {(2x)² + 2•2x•3 + 3² - 3²}= - {(2x + 3)² - 3²}

-4x² - 12x= - (4x² + 12x)= - {(2x)² + 2•2x•3 + 3² - 3²}= - {(2x + 3)² - 3²}= - (2x+3 + 3)(2x+3 - 3)

-4x² - 12x= - (4x² + 12x)= - {(2x)² + 2•2x•3 + 3² - 3²}= - {(2x + 3)² - 3²}= - (2x+3 + 3)(2x+3 - 3)= - (2x + 6) 2x

-4x² - 12x= - (4x² + 12x)= - {(2x)² + 2•2x•3 + 3² - 3²}= - {(2x + 3)² - 3²}= - (2x+3 + 3)(2x+3 - 3)= - (2x + 6) 2x= (2x + 6)(-2x)
