Question 117946: Hi, this question is a multiple choice question from the pre-ACT test. I don't even know where to start with this one, I tried solving for x, and I tried to put the answer choices in the problem, but to no avail. I believe this is an identity but I can't figure out how to use that knowledge to solve this. This problem has frustrated me for 2 days.
In the equation, x^2 + 16x + a = (x + b)^2, a and b are constants. If the equation is true for all values of x, what is the value of a?
the answer choices are: 4, 8, 16, 64, or 256. The correct answer is 64 but I have no idea how to work out the problem to get that answer. Please help me figure this problem out.
thanks for your help!
