Question

5a³-20ab² Винести за дужки

Answer 1

Ответ:

выносим за скобки общий множитель

5а³-20ab²=5a(a²-4b²)=5a(a-2b)(a+2b).

Объяснение:

разность квадратов

а²-б²=(а-б)(а+б).

Answer 2

$5a^3-20ab^2=5a(a^2-4b^2)=5a(a-2b)(a+2b)$

Answer 3

To factor the expression 5a³ - 20ab², we can look for common factors among the terms. In this case, the common factor is 5a. We can factor out 5a from each term to get:

5a(a² - 4b²)

Now, let's focus on factoring the expression inside the parentheses, a² - 4b². This is a difference of squares, which can be factored using the formula (a - b)(a + b). In this case, a represents a and b represents 2b. Applying the formula, we get:

5a(a - 2b)(a + 2b)

Therefore, the fully factored expression is 5a(a - 2b)(a + 2b).
