x = 2 or x = -4

Step-by-step explanation:

Solve for x over the real numbers:

-x^2 - 2 x + 8 = 0

Multiply both sides by -1:

x^2 + 2 x - 8 = 0

Add 8 to both sides:

x^2 + 2 x = 8

Add 1 to both sides:

x^2 + 2 x + 1 = 9

Write the left hand side as a square:

(x + 1)^2 = 9

Take the square root of both sides:

x + 1 = 3 or x + 1 = -3

Subtract 1 from both sides:

x = 2 or x + 1 = -3

Subtract 1 from both sides:

x = 2 or x = -4

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
