To square the expression (x-3)^2, we multiply it by itself:
(x-3)(x-3) = x^2 - 3x - 3x + 9
= x^2 - 6x + 9
So, the expression becomes:
(x^2 - 6x + 9) - 12
= x^2 - 6x + 9 - 12
= x^2 - 6x - 3
Therefore, the squared and simplified expression is x^2 - 6x - 3.
(x-3)(x-3) = x^2 - 3x - 3x + 9
= x^2 - 6x + 9
So, the expression becomes:
(x^2 - 6x + 9) - 12
= x^2 - 6x + 9 - 12
= x^2 - 6x - 3
Therefore, the squared and simplified expression is x^2 - 6x - 3.
