# C1 Question Watch

1. Find the set of values of X for which 9x^2 +12x +7 > 19

------------

I'm confused on how to start this off ?

Do I bring the 19 to the left then factorise ?
2. Yes that's the right approach. Once you've factorised, sketch the graph of your inequality and you should be able to interpret which x ranges satisfy it.
3. Do I see where it is greater than zero when sketching or greater than 19 ?

After factorising the quadratic you should have two solutions.

X will be greater than the higher one, or less than the lower one, as the question was 'greater than'.
5. I got the answer, thanks everyone
