I'm doing a practice test we received for hw. It has been a while since I have taken a math class and the prof says this is supposed to be a refresher for us. But these three problems seem like a foreign language. I am having a hard time remembering how to do some of the problems.If you can point me in the right direction would help out, thanks
9. Determine the constant that should be added to the binomial so that it becomes a perfect - square trinomial. Then write and factor the trinomial.
x2( x is squared ) + 1 over 6 (fraction) an x is next to the fraction
10. Solve 7x2( squared ) + 10x + 2 = 0
11. Solve x2(squared) + 14x + 38 = 0
