Question

What value is added to both sides of the equation x2 − 4x = −2 in order to solve by completing the square

Answer 1

Take the coefficient of the x term.
Divide it by 2.
Then square it.

Answer 2

okay so it would be 4

Answer 3

yeah you divide -4 by 2

Answer 4

it would be -2 then adding -2 square on both sides for completing square

Answer 5

So we take the equation
x2 − 4x = −2
then add 4 to both sides
x2 − 4x +4 = −2 +4

Now we take the square root of both sides

x-2 = sq root (2)
