Question

Дано: p₁=-3-5a, p₂=3a-2. Найти: p₁-p₂. 1)-8а-1 2)8а-1 3)2а-1

Answer 1

Вариано ответа будет А

Answer 2

To find $p_1 - p_2$, you simply subtract the second expression from the first:

$p_1 - p_2 = (-3 - 5a) - (3a - 2)$

Let's simplify this expression:

$p_1 - p_2 = -3 - 5a - 3a + 2$

Now, combine like terms:

$p_1 - p_2 = (-5a - 3a) + (-3 + 2)$

$p_1 - p_2 = -8a - 1$

So, the correct answer is option 1) $-8a - 1$.
