Question

(x-3)(3+1)-(2x+3)(4х-1)​

Answer 1

Ответ:

При упрощении выражения получится $-8x^{2} - 6x - 9$

Answer 2

Ответ:

3x+x-9-3-(8x²-2x+12x-3)=3x+x-9-3-8x²+2x-12x+3=-6x-8x²-9

Answer 3

To simplify the expression $(x-3)(3+1)-(2x+3)(4x-1)$, you can follow these steps:

1. Distribute the terms within each set of parentheses:

   $(x-3)(3+1) = x(3) + x(1) - 3(3) - 3(1) = 3x + x - 9 - 3$

   $(2x+3)(4x-1) = 2x(4x) + 2x(-1) + 3(4x) + 3(-1) = 8x^2 - 2x + 12x - 3$

2. Now, simplify the expressions obtained:

   $(x-3)(3+1) = 3x + x - 9 - 3 = 4x - 12$

   $(2x+3)(4x-1) = 8x^2 - 2x + 12x - 3 = 8x^2 + 10x - 3$

3. Subtract the second expression from the first expression:

   $(4x - 12) - (8x^2 + 10x - 3)$

4. Distribute the negative sign through the second expression:

   $4x - 12 - 8x^2 - 10x + 3$

5. Combine like terms:

   $-8x^2 + 4x - 10x - 12 + 3$

6. Combine like terms further:

   $-8x^2 - 6x - 9$

So, the simplified expression is $-8x^2 - 6x - 9$.
