I'm pretty sure the answer is independent because the sex of her other children has nothing to do with the sex of her new baby. I may be wrong though.<span />
Answer:
p =
, q = 9
Step-by-step 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(
)x +
-
)
= 4(x +
)² - 4 × 
= 4(x +
)² - 9
(6•x) + 7 = 8
6x + 7 = 8
6x = 1
X = 1
