Subtract 16 to get
x^2 -25 = 0
Factor this as
(x -5)(x +5) = 0
The zero product property tells you the product will be zero when one of the factors is zero.
For x-5 = 0
x = 5
For x+5 = 0
x = -5
The appropriate choice is
3) x=-5 or x=5
The answer is 9/2. You can use desmos scientific calculator to quickly convert the decimal into an improper fraction or any conversion from decimal to fraction.

I'll add a picture so it can make more sense to you. :)
We'll use the picture below as an example okay? :)
What you want to do is m<span>ultiply the numerator (top number) of the left-hand fraction by the denominator (bottom number) of the right-hand fraction. Then multiply the numerator (top number) of the right-hand fraction by the denominator (bottom number) of the left-hand fraction. Next step is to set the two products equal to each other. Then s<span>olve for the variable. If you look at the picture while reading the steps, then I think it'll make more sense.
I really hope this helps :)</span></span>
