13x-42

Answer 3

To simplify the expression, let's expand the product on the right-hand side using the distributive property:

(x - 6) × (x - 7) = x × (x - 7) - 6 × (x - 7)

Now, let's simplify each term:

x × (x - 7) = x² - 7x -6 × (x - 7) = -6x + 42

Substituting these simplified terms back into the expression, we have:

x² - (x - 6) × (x - 7) = x² - (x² - 7x) - (-6x + 42)

Now, let's simplify further:

x² - (x² - 7x) - (-6x + 42) = x² - x² + 7x + 6x - 42

Combining like terms:

x² - x² + 7x + 6x - 42 = 13x - 42

Therefore, the simplified form of the expression x² - (x - 6) × (x - 7) is 13x - 42.
