Question

(a² + 5a +4) - (a² +5a-4)​

Answer 1

Объяснение:

$(a {}^{2} + 5a + 4) - (a {}^{2} + 5a - 4) = a {}^{2} + 5a + 4 - a {}^{2} - 5a + 4 = 5a + 4 - 5a + 4 = 4 + 4 = 8$

Answer 2

Ответ:

(а²+5а+4)-(а²+5а-4)=а²+5а+4-а²-5а+4=8

Answer 3

To simplify the expression (a² + 5a + 4) - (a² + 5a - 4), you can use the distributive property to remove the parentheses and then combine like terms:

(a² + 5a + 4) - (a² + 5a - 4)

First, distribute the negative sign to both terms inside the parentheses:

a² + 5a + 4 - a² - 5a + 4

Now, combine like terms:

(a² - a²) + (5a - 5a) + (4 + 4)

The terms with a² cancel each other out, and the terms with 5a also cancel each other out:

0 + 0 + 8

So, the simplified expression is 8.
