Question

(5-a)(5+a) = я незнаю как єво ришить

Answer 1

Ответ:

ну посоветовать я тебе могу выучить эту формулу:

$(a - b)(a + b) = {a}^{2} - {b}^{2} (a - b)(a + b) = {a}^{2} - {b}^{2}$

${5}^{2} - {a}^{2}$

$25 - {a}^{2}$

Answer 2

To solve the expression (5 - a)(5 + a), you can use the distributive property of multiplication over addition. Here's how you can do it:

Step 1: Apply the distributive property. (5 - a)(5 + a) = 5(5) + 5(a) - a(5) - a(a)

Step 2: Simplify each term. = 25 + 5a - 5a - a^2

Step 3: Combine like terms. The terms 5a and -5a cancel each other out. = 25 - a^2

So, the simplified expression for (5 - a)(5 + a) is 25 - a^2.
