Answer:

Step-by-step explanation:
(1) To solve by factoring,
Given equation: 
Subtract 9 from both sides of the equation.

Using zero factor principle, 
The solutions are
.
(2) To solve by complete the square
,
Given 
Divide both sides of the equation by 4.
Square root on both sides.

(3) To solve by quadratic formula,

Here, a = 4, b = 0, c = –9
Quadratic formula,
