Simplify (2z – 3)2. (1 point) Responses 4z2 – 9 4 z 2 – 9 4z2 – 9z 4 z 2 – 9 z 4z2 – 12z – 9 4 z 2 – 12 z – 9 4z2 – 12z + 9
The given expression is (2z - 3)^2.
Expanding this expression gives (2z - 3)(2z - 3) which can be simplified to (4z^2 - 6z - 6z + 9).
Combining like terms, we get 4z^2 - 12z + 9.
Therefore, the simplified expression is 4z^2 - 12z + 9.
