Solve for x:9x^249=0

SIMPLE! add 49 to the other side
9x^2=49
Now take the square root of 49. I'm in 10th grade, isnt this easy? maybe im doing it wrong? 
9x^2=49
3x=7
x=7/3 
stupid 10th grader

positive or negative 7/3
stupid whoever u are 
X equals minus seven over 3 or seven over three. We've been dealing with this in my school so I'm certain as death about it.

+7/3
