Question

(x – 7) (x + 8) Срочно

Answer 1

$(x - 7)(x + 8) = {x}^{2} + 8x - 7x - 56 = {x}^{2} + x - 56$

Answer 2

Ответ:

x^2+8x-7x-56=x^2+x-56

Answer 3

To simplify the expression (x - 7)(x + 8), you can use the distributive property, also known as FOIL (First, Outer, Inner, Last). Here's the step-by-step process:

1. Multiply the First terms: x * x = x^2

2. Multiply the Outer terms: x * 8 = 8x

3. Multiply the Inner terms: -7 * x = -7x

4. Multiply the Last terms: -7 * 8 = -56

Now, combine all the results:

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

Combine like terms (8x and -7x):

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

So, the simplified expression is: x^2 + x - 56.
