Question

1)2m+q+q-4m 2)3a+2b-b-a. 3)x²+3y²+4x-y²b 4)5a²-4b²-3a²+b²​

Answer 1

Ответ:

Пошаговое объяснение:

1)2m+q+q-4m=-2m+2q = 2(q-m)

4)2а^2-4b^2+y^2=2a^-3b^2

2)3a + 2b - b - a = (2b - b) + (3а-а) = b + 2a

Answer 2

I can help you simplify these expressions:

1. 2m + q + q - 4m Combine like terms: 2m - 4m + q + q -2m + 2q

2. 3a + 2b - b - a Combine like terms: 3a - a + 2b - b 2a + b

3. x² + 3y² + 4x - y²b Combine like terms: x² + 4x + 3y² - y²b

4. 5a² - 4b² - 3a² + b² Combine like terms: 5a² - 3a² - 4b² + b² (5a² - 3a²) + (-4b² + b²) 2a² - 3b²

So, the simplified expressions are:

1. -2m + 2q
2. 2a + b
3. x² + 4x + 2y² - y²b
4. 2a² - 3b²
