Ramlah Merchant Posted March 15, 2017 Share Posted March 15, 2017 The equation given is a= 5b^2+ 10b + 7 Which is greater- a or b? They say to do it by completing the square but I simply do not understand their solution! Please help me out with the easiest solution.

prasku Posted April 1, 2017 Share Posted April 1, 2017 Hi Ramlah , Did you get the solution ? Quote Link to comment Share on other sites More sharing options...
frogs Posted July 9, 2017 Share Posted July 9, 2017 Hey so in here, there's really two cases: We see that a depends on b. So if b>0, then obviously a > b. If b0 and thus a>b here too. So in the final answer, we see that a > b for both situations. So choice that says a>b is correct Quote Link to comment Share on other sites More sharing options...
