Х²+3 2²-5=

To evaluate the expression, we need to substitute the value of x into the first equation and calculate the second equation.

For the first equation, since we don't have a specific value for x, we can't simplify it further.

For the second equation:

2² - 5 = 4 - 5 = -1

Therefore, the value of 2² - 5 is -1.
