i know that but can you show me the solution by using the formula - B ± √ B2-4AC
x = ————————
2A
- B ± √ B2-4AC
x = ————————
2A
-(0) ±√ (0)2-4(9)(-72)
x=_______________
2(9)
±√2592
x=____
18
then thats the answer

Ewan.. 

transpose -72 to the right. then, then divide both side by 9.. the answer will be x squared = 8... then, get the square root of both sides. the answer will be: x = 2 square root of two...
 di ko talaga alam,, ehh.
