6х-3+16хквадрат-72х-2х+9

-68х+6+16хквадрат

16хквадрат-68х+6

Answer 2

To simplify the expression, follow the order of operations (PEMDAS/BODMAS - Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction):

Given expression: 3(2x-1) + (8x-1) - (2x-9)

Let's simplify step by step:

1. Distribute the 3 to both terms inside the first set of parentheses: 3 * 2x - 3 * 1 + (8x-1) - (2x-9)

   This becomes: 6x - 3 + 8x - 1 - (2x - 9)

2. Distribute the negative sign to both terms inside the second set of parentheses: 6x - 3 + 8x - 1 - 2x + 9

3. Combine like terms: (6x + 8x - 2x) + (-3 - 1 + 9)

   Simplifying the coefficients: 12x + 5

So, the simplified expression is: 12x + 5
