(x2 + 16 = 36) what is x?
Is that suppose to be 2X or X^2
If it is 2x, x would be 10.
2x + 16= 36
-16 -16
2x=20
/2 /2
x=10
If it is x^2,
x^2+16=36
x^2=20
x= plus or minus square root of 20
x= plus or minus (2 * square root 5).
To find the value of x in the equation (x^2 + 16 = 36), we can follow these steps:
Step 1: Subtract 16 from both sides of the equation to isolate the term with x^2.
x^2 + 16 - 16 = 36 - 16
x^2 = 20
Step 2: Take the square root of both sides of the equation.
√(x^2) = √(20)
x = ±√20
Step 3: Simplify the square root of 20.
x ≈ ±4.47
Therefore, x can be approximately equal to ±4.47.
