for

if a=1, and , then it comlpetes the square

a=1, b=12

since a=1, c=

add 36 to both sides of the nonexistant equation to copmlete square

-362

step-by-step explanation:

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

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /
