Question

(a-1)-(a-2) пж пж пж пж пж

Answer 1

$(a - 1) - (a - 2) = 1$

Пошаговое объяснение:

$(a - 1) - (a - 2)$

$a - 1- a + 2$

$1$

Answer 2

To simplify the expression (a-1)-(a-2), we can distribute the negative sign to each term within the parentheses.

(a-1) - (a-2) = a - 1 - a + 2

Next, we can combine like terms. The terms "a" and "-a" will cancel each other out.

a - a - 1 + 2 = -1 + 2

Finally, we can simplify the remaining terms.

-1 + 2 = 1

Therefore, (a-1)-(a-2) simplifies to 1.
