Xto the second - 6x+9=25 value of x

-2, 8 is your answer

Step-by-step explanation:

x² - 6x + 9 = 25

First, set the equation equal to 0. Subtract 25 from both sides

x² - 6x + 9 (-25) = 25 (-25)

x² - 6x + 9 - 25 = 0

x² - 6x - 16

Do Reverse FOIL

x² - 6x - 16

x          -8

x            2

(x - 8)(x + 2) = 0

Solve for x. Set each parenthesis = 0

x - 8 = 0

x + 2 = 0

Isolate the x in both scenarios

x - 8 = 0

x - 8 (+8) = 0 (+8)

x = 8

x + 2 = 0

x + 2 (-2) = 0 (-2)

x = 0 - 2

x = -2

The values of x is -2, 8
