I have worked on my math for 8 hours straight.. my brain has melted but I learned a lot today. I have 2 problems left and can not seem to get them... Can anyone show me how to work them out?

1) solve the quadratic equation...

4xsquared=13x +12

and the other is...

2) Factor Completly

9x squared+12xy+4y squared-25

I dont have long to turn this in so it is kind of urgent.. any help is GREATLY appreciated.. Thanks so much.. Heather
