Answer 2

To evaluate the expression (x²+3²-2x²)+(x-1)² when x=2, we substitute the value of x into the expression and perform the calculations.

Let's substitute x=2 into the expression: (2² + 3² - 2(2)²) + (2-1)²

Now we simplify each term: (4 + 9 - 2(4)) + (1)² (4 + 9 - 8) + 1 (13 - 8) + 1 5 + 1 6

Therefore, when x=2, the expression (x²+3²-2x²)+(x-1)² equals 6.
