Question

vertex form:\[y=x^2+10x+32\]

Answer 1

after completing the square i keep getting \(y=(x-5)^2+7\) but the answer is \(y=(x+5)^2+7\)

Answer 2

You completed the square wrong. No way should you get (x-5)

Answer 3

can you show me?

Answer 4

will*

Answer 5

\[ y=x^2+10x+32 \\y - 32 = x^2 + 10 \\ y - 32 + 25 = x^2 + 10 + 25\\ y - 7 = (x+5)^2 \\ y = (x + 5)^2 + 7\]

Answer 6

i think i get it now...thanks

Answer 7

I know they teach these in a weird way. They try to show you how to complete the square without subtracting the 32 from both sides, but doing it that way is silly.

Answer 8

yeah i know thanks though...i see it, i was skipping steps
