so 1/9-16z^2 this is a diffirence of two perfect squares thing so (1/3)^2-(4z)^2 so ((1/3)-4z)((1/3)+4z)
The expression 9 1 − 16 z 2 can be factored using the difference of squares formula. The factored form is ( 3 1 − 4 z ) ( 3 1 + 4 z ) . This approach involves identifying the square roots of each term in the expression.
