x = 9 and x = -1
Step-by-step explanation:
This equation should be written all on one line:
2(x - 4)^2 = 50
using " ^ " to denote exponentiation.
Dividing both sides by 2 yields
(x - 4)^2 = 25
We must solve for x - 4, and then for x alone:
Taking the square root of both sides, we get:
x - 4 = ±5
which yields two separate solutions: x = 9 and x = -1
