Billie solved the equation below by completing the square, but she got the incorrect solution. in which step did billie first make an error? choices: 1234

step 1: x^2+10x=49

step 2: x^2+10x+25=49

step 3: (x+5)^2=49

step 4: x+5=+-7

step 5: x=2, x=–12

step 2

Step-by-step explanation:

we have

---> given problem

step 1

Move the constant to the right side

the step 1 is correct

step 2

Complete the square

The step 2 is not correct

step 3

Rewrite as perfect squares

step 4

take square root both sides

step 5

Find the values of x

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
