Answer:

2x² - 19x + 42

Explanation:

We want to expand (x - 6)(2x - 7) into a trinomial.

We use the FOIL (first, outer, inner, last) method.

First, multiply the first terms of each parenthetical expression; in the first one, that's x, and in the second, that's 2x:

x * 2x = 2x²

Next, multiply the outer terms; in the first one, that's x, and in the second, that's -7:

x * (-7) = -7x

After that, multiply the inner terms; in the first one, that's -6 and in the second, that's 2x:

(-6) * 2x = -12x

Finally, multiply the last terms; in the first one, that's -6 and in the second, that's -7:

(-6) * (-7) = 42

Now, add all these results together:

2x² + (-7x) + (-12x) + 42

2x² - 19x + 42

The answer is thus 2x² - 19x + 42.
