Solve x 2 - 4x - 7 = 0 by completing the square. What are the solutions?
Bingel [31]

Answer:

x = 2±sqrt(11)

Step-by-step explanation:

x^2 -4x - 7 =0

Add 7 to each side

x^2 -4x -7+7 =0+7

x^2 -4x =7

To complete the square take the coefficient of the x term and  divide by 2 and then square it.  Add it to both sides

-4 /2 = -2 then square

(-2)^2 = 4

Add 4 to both sides

x^2 -4x+4 =7+4

x^2 -4x+4 = 11

Factor the left side into (x-b/2)^2

(x-2)^2 =11

Take the square root of each side

sqrt((x-2)^2) =±sqrt(11)

x-2 = ±sqrt(11)

Add to to each side

x-2+2 = 2±sqrt(11)

x = 2±sqrt(11)

Find XY when X(-7, 10) and Y(3, 4).
kobusy [5.1K]

The length of XY, using the distance formula, is approximately: 11.7 units.

<h3>How to Apply the distance Formula to Find the Length of a Segment?</h3>

The distance formula given to find the distance between two points or the length of a segment, is given as: d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}.

We are given the coordinates of the endpoints of the line segment as follows:

X(-7, 10) and Y(3, 4).

Let (x1, y1) represent X(-7, 10)

Let (x2, y2) represent Y(3, 4)

Plug in the values of the coordinates of the endpoints into the distance formula:

XY = √[(3−(−7))² + (4−10)²]

XY = √[(10)² + (−6)²]

XY = √(100 + 36)

XY = √136

XY ≈ 11.7 units

Thus, the length of XY, using the distance formula, is approximately calculated as: 11.7 units.
