Answer:
-4, 0
Step-by-step explanation:
The denominator is x^2+4x. This is zero when ...
x^2 +4x = 0
x(x +4) = 0
The zero product rule tells you the product is zero when the factors are zero.
x = 0
x +4 = 0 ⇒ x = -4
The denominator is zero for x=0 and x=-4.

ANSWER = 21
a² - b² = (a - b)(a + b)
49x² - 9 = (7x)² - 3² = (7x - 3)(7x + 3)
