Answer 3

To expand the expression (x+1)(x-2), you can use the distributive property. Multiply each term in the first set of parentheses by each term in the second set of parentheses and combine like terms if necessary.

(x+1)(x-2) can be expanded as follows:

(x+1)(x-2) = x(x-2) + 1(x-2)

Now, let's multiply each term:

x(x-2) + 1(x-2) = x^2 - 2x + x - 2

Simplifying further:

x^2 - 2x + x - 2 = x^2 - x - 2

So, the expanded form of (x+1)(x-2) is x^2 - x - 2.
