Hi there!
Rewrite 16:
The difference of squares rule states that
. With this, apply the difference of squares to the equation:
The zero-product property states that if the product of two numbers is 0, then one of the numbers must be equal to zero. Set each term equal to 0 and find the solutions:
Therefore, the solutions are -4 and 4.
I hope this helps!
