Rewrite the equation by completing the square. x^2 −16x+63=0 (x +{ })^2={ }

Elina [12.6K]

Answer:

(x + 4) ^{2} + 47 = 0

Step-by-step explanation:

$(x ^{2} + 4 ^{2} ) - 4 ^{2} + 63 = 0 \\ (x + 4) ^{2} + 47 = 0$

When completing squares, basing on our equation in the question:

First square the half of 16 e.g (16÷2)^2 = 4^2

Add the result to x^2 and subtract it with 63 e.g the second equation

I'm not 100% sure if I am right, but for number 9 you would pick two points on , let's just say you pick points (0, 1) and (2, -2). Then you would find those points in the table. So in this case the answer would be D. And I'm not really sure how to explain #10 but you basically work out each problem with the graph to see if it makes sense. For example if you try working out problem F it wouldn't make sense since you start of with 10 dollars and earn 2 each day. But on the graph it shows that you are loosing two. Sorry if I didn't explain it right, if you have more questions let me know!
