I will assume you mean,
X2 - 16 = 0
X2 = 16
take square root each side
X = (+/-) 4
=========
(-4, 0) and (4, 0)

What is the solution equation x2 equals 16?
-4 and 4
What is the solution set of x2 equals 36?
x = { +6, -6 }
Solution set of x2 plus 49 equals 0?
x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i
Which values are solution to the inequality of x2 equals 64?
x2≤64
How do you solve x2 equals 16?
If you meant x2 = 16 then take square root both sides which gives x = 4 but you need to see that -42 is also 16 so that is another solution. The two solutions are 4 and -4.

What is the Solution Set of x2 - 16 < 0?
do it yourself
What is the solution set of x2 equals 36?
x = { +6, -6 }
Solution set of x2 plus 49 equals 0?
x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i
What is the solution set of x2-7x-18 equals 0?
Using the quadratic formula, I found the solution set is x=2,x=-9
Which values are solution to the inequality of x2 equals 64?
x2≤64
What is the solution to the inequality x2 equals 16?
If x2 = 16 then this is not written as an inequality.An inequality tells us that one thing is not equal to another.The above is an equation, because it is telling us that one thing is equal to another.If x2 = 16 then x = 4 & -4.

X2 plus 6x-16 equals?
Equals anything... x is a variable. If that equation was set equal to zero then you could solve for x, but that is not what you have asked.
What is the solution to the inequality x2 16?
if x2 ≠ 16, then: {x | x ∈ ℜ, x ∉ (4, -4)}
What is the solution set of x2-2x-24?
(-4,6)
Solution set of y equals x2 - x - 6?
-4
