Question

(3a-7b) 15ab + (2a+2b) 15ab =?​

Answer 1

Ответ:

75ab (a - b) или 75a²b - 75b²a

Объяснение:

(3a-7b) 15ab + (2a+2b) 15ab = 45a²b - 105ab² + 30a²b + 30b²a = 75a²b - 75b²a = 75ab (a - b)

Answer 2

To solve the expression $(3a-7b) \cdot 15ab + (2a+2b) \cdot 15ab$, we'll use the distributive property of multiplication:

$(3a-7b) \cdot 15ab + (2a+2b) \cdot 15ab$

$= 45a^2b - 105ab^2 + 30ab^2 + 30ab^2$

$= 45a^2b - 45ab^2$

So, $(3a-7b) \cdot 15ab + (2a+2b) \cdot 15ab = 45a^2b - 45ab^2$.
