Answer 2

(22-1)(11+3)-(11-2)(22-2)=21*14-9*20=
=294-180=114

Answer 3

To find the value of the expression (2x-1)(x+3) - (x-2)(2x-2) when x=11, you just need to substitute x with 11 and perform the calculations.

Let's do the math step-by-step:

1. Replace x with 11: (211 - 1)(11 + 3) - (11 - 2)(211 - 2)

2. Simplify the expressions within parentheses: (22 - 1)(14) - (9)(20)

3. Perform the multiplications: (21)(14) - (9)(20)

4. Perform the remaining multiplications: 294 - 180

5. Subtract: 294 - 180 = 114

So, when x=11, the expression (2x-1)(x+3) - (x-2)(2x-2) equals 114.
