Question

1. (6x²-2x)+(5+10x-5x²)= 2. (6xy+8y)-(2xy+8y-1)=

Answer 1

Объяснение:

1. (6x²-2x)+(5+10x-5x²) = 6x²-2x+5+10x-5x² = x²+8x+5

2. (6xy+8y)-(2xy+8y-1) = 6xy+8y-2xy-8y+1 = 4xy+1

Answer 3

Let's simplify each expression step by step:

1. (6x² - 2x) + (5 + 10x - 5x²)

Step 1: Combine like terms within the parentheses: 6x² - 2x + 5 + 10x - 5x²

Step 2: Combine like terms outside the parentheses: (6x² - 5x²) + (-2x + 10x) + 5

Step 3: Simplify the terms: 1x² + 8x + 5

So, the simplified expression is: 1x² + 8x + 5 (or just x² + 8x + 5).

2. (6xy + 8y) - (2xy + 8y - 1)

Step 1: Distribute the negative sign to all terms inside the parentheses: 6xy + 8y - 2xy - 8y + 1

Step 2: Combine like terms: (6xy - 2xy) + (8y - 8y) + 1

Step 3: Simplify the terms: 4xy + 1

So, the simplified expression is: 4xy + 1.
