9514 1404 393

  (x -7)^2 -9 = 0

Step-by-step explanation:

To complete the square, add and subtract the square of half the x-coefficient.

  x^2 -14x +40 = 0 . . . . given

  x^2 -14x +(-7)^2 +40 -(-7)^2 = 0

  (x -7)^2 +40 -49 = 0

  (x -7)^2 -9 = 0

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
