Answer 2

( x - 2 ) · ( x + 5 ) - 3x = x² + 5x - 2x - 10 - 3x = x² - 10 .

Answer 3

The expression you provided is:

(x - 2)(x + 5) - 3x

To simplify this expression, you can use the distributive property to multiply the terms inside the parentheses and then combine like terms:

(x - 2)(x + 5) - 3x

= x(x) + x(5) - 2(x) - 2(5) - 3x

Now, perform the multiplications:

= x^2 + 5x - 2x - 10 - 3x

Next, combine like terms:

= x^2 + (5x - 2x - 3x) - 10

= x^2 + 0x - 10

= x^2 - 10

So, the simplified expression is:

x^2 - 10
