Solve x2 – 8x = 3 by completing the square. which is the solution set of the equation?

x = 4 ±

Step-by-step explanation:

Given

x² - 8x = 3

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 4)x + 16 = 3 + 16

(x - 4)² = 19 ( take the square root of both sides )

x - 4 = ± ( add 4 to both sides )

x = 4 ±

Step-by-step explanation:

x²-8x=3

add (-4)² or 16

x²-8x+16=3+16

(x-4)²=19

x-4=±√19

x=4±√19

 is that Emilia inequality is correct because the number of hours is less than or equal too but then Emilia number line is incorrect . The endpoint should not be filled in and the number line should be shaded to the left of the endpoint it is because of how the sign is less than or equal to 6 but in the number line it says that it may be six and greater than due to how the arrow is going to the right but it is supposed to go to the left because of how it six or less than six
