Answer 2

1) 6х^2-3х+4х-2-6х^2-9х+2х
2) -3х+4х-2-9х+2-6х-2
3) -6х-2

Answer 3

To simplify the expression (3x + 2)(2x - 1) - 3x(2x + 3) + 2x, you can follow these steps:

Step 1: Distribute the terms inside the parentheses: (3x + 2)(2x - 1) = 3x * 2x + 3x * (-1) + 2 * 2x + 2 * (-1) = 6x^2 - 3x + 4x - 2

Step 2: Combine like terms within the first parentheses: = 6x^2 + (4x - 3x) - 2

Step 3: Simplify further by combining like terms: = 6x^2 + x - 2

Now, you need to subtract the expression 3x(2x + 3) from the result we just obtained:

Step 4: Distribute the -3x to the terms inside the second parentheses: -3x(2x + 3) = -3x * 2x - 3x * 3 = -6x^2 - 9x

Step 5: Subtract this expression from the previous result: (6x^2 + x - 2) - (-6x^2 - 9x)

Step 6: Remove the parentheses when subtracting by distributing the negative sign: = 6x^2 + x - 2 + 6x^2 + 9x

Step 7: Combine like terms: = (6x^2 + 6x^2) + (x + 9x) - 2

Step 8: Continue combining like terms: = 12x^2 + 10x - 2

So, the simplified expression is 12x^2 + 10x - 2.
