Which of the following is the result of the equation below after completing the square and factoring? x^2-4x+2=10

Answer:

B. (x-2)^2=12

Step-by-step explanation:

The constant that completes the square is the square of half the coefficient of the x-term. That value is (-4/2)^2 = 4.

There is already a constant of 2 on the left side of the equal sign, so we need to add 2 to both sides to bring that constant value up to 4.

x^2 -4x +2 = 10 . . . . . . . given

x^2 -4x +2 +2 = 10 +2 . . . . complete the square (add 2 to both sides)

(x -2)^2 = 12 . . . . . . . . . write as a square

Answer:

w = 33

Step-by-step explanation:

w ÷ 3.3 = 10

multiply both sides by 3.3:

w ÷ 3.3 x 3.3 = 10 x 3.3

⇒ w = 33

Rewrite the equation without absolute value, thanks!

34kurt

Since x - 3 < 0 for -2 < x < 3, |x-3| = -(x-3)

Since x + 2 > 0 for -2 < x < 3, |x+2| = x+2

Since x - 5 < 0 for -2 < x < 3, |x-5| = -(x-5).

So y = -(x-3) + (x+2) -(-(x-5)) = 3 - x + x + 2 + x - 5 = x.

y = x, if -2 < x < 3.
