Simplify (x + 7)(x + 5).
To simplify (x + 7)(x + 5), we can use the distributive property:
(x + 7)(x + 5) = x(x) + x(5) + 7(x) + 7(5)
= x^2 + 5x + 7x + 35
= x^2 + 12x + 35
Therefore, (x + 7)(x + 5) simplifies to x^2 + 12x + 35.

To simplify (2z - 3)2, we need to multiply 2 by (2z - 3):
= 2 * (2z - 3)
= 4z - 6
Therefore, (2z - 3)2 simplifies to 4z - 6.
