Solve (x – 3)2 = 49. Select the values of x.

–46

-4

Which values are solutions of the equation? Check all of the boxes that apply.

Option

Choose the solutions to the quadratic equationx2 – 8x – 9 = 0.

–21

–1

Choose the solution to the equation.

Option

Given 2x² = -8, x is .

-2

2i or -2i

4i or -4i

Choose an equation that would be used to solve 0 = -x2 + 10x – 8

(x + 25)2 = –8

(x – 5)2 = 17

(x – 10)2 = 25

x + =

1/4

1/2

2/3

Now that you have x² - 8x + 16 = 9 + 16, apply the square root property to the equation.

(x – 4)² = 25

(x + 16)² = 25

(x – 4)² = 9

(x + 16)² = 9
