Best ResponseYou've already chosen the best response.0What I'm confused on is the number which will fill the blank space. It should be 2.25 but this would make factoring difficult.

Best ResponseYou've already chosen the best response.1Think hard on this: \((a+b)^{2} = a^{2} + 2ab + b^{2}\) Don't use decimals. (3/2)^2 = 9/4 It will NEVER make factoring difficult. You are Completing the square. It is, by design, easy to factor after that. The factoing will always be \((a+b)^{2}\)  every time.

Best ResponseYou've already chosen the best response.0Oh, I see now. So it will be (x + 3)^2 and then I will add 9/4 to 4. Thank you!!
