What number must you add to complete the square?

Whenever you complete a square, you're really taking this:

(x+b)^2=x^2+2bx+b^2 [/tex]

And equating roots. Here, the b is clearly 11 (2b=22 implies b=11), so that means we want 121 as our ending number. That means we should add 121 to both sides to get:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
