Question

7*(x+8) +(x-8) *(x+8)​

Answer 1

Ответ:

$8 {x}^{2} - 57x + 56$

Answer 2

To simplify the expression 7*(x+8) + (x-8)*(x+8), you can follow these steps:

1. Distribute the constants (7) and (x-8) to the terms inside the parentheses:

   7*(x+8) + (x-8)(x+8) = 7x + 78 + x(x+8) - 8*(x+8)

2. Simplify the expressions within the parentheses:

   7x + 56 + x(x+8) - 8*(x+8)

3. Distribute x to the terms inside the second set of parentheses:

   7x + 56 + x^2 + 8x - 8(x+8)

4. Distribute -8 to the terms inside its set of parentheses:

   7*x + 56 + x^2 + 8x - 8x - 64

5. Combine like terms:

   7*x + 8x - 8x + 56 - 64

6. Simplify further:

   7x - 8x + 56 - 64

7. Combine like terms:

   -x - 8

So, the simplified expression is:

• x - 8
