I need to make 8x^2+36x a perfect square, which number would i add to it to do so?(this is for parametric sequences in calc 2, but i just need to know the number i use to make that part a perfect square)
The idea here is that you want to write an equation such that , so you have to come up with a way to solve for c and . In this case you want to know .One thing we know about squaring an polynomial of the form is that b from above can be given by . Therefore in your case you can solve for c and square it to get the value you need, i.e. solve for c in the following and then square the result
