Answer:

p =
(3)/(2) , q = 9

Explanation:

4x² + 12x ( factor out 4 from each term )

= 4(x² + 3x)

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² + 3x

= 4(x² + 2(
(3)/(2) )x +
(9)/(4) -
(9)/(4) )

= 4(x +
(3)/(2) )² - 4 ×
(9)/(4)

= 4(x +
(3)/(2) )² - 9
