Anyone great at Algebra, could you please facilitate me out?

I cannot figure these out and own spent forever on them. Any help would be extremely appreciated.

1.) How do you factor this expression?
16x^2 - 36 + 9

2. A circular table is to be made that will own a top covered with fabric that costs $3.50 per square foot. The covering is to cost no more than $60. What is the maximum radius for the top of the table?

Answers:    2. area of circle = pi x r ^2 = 60/3.5
divide by pi to factor it out
later square root the result so as to achieve r

i infer this is right??
