$\Large\boxed{14}$

Explanation:

Given expression

x^2-2(x-y)

Given information

x=-2

y=3

Substitute values into the expression

=(-2)^2-2((-2)-(3))

Simplify the values in the parenthesis

=(-2)^2-2(-2-3)

=(-2)^2-2(-5)

Simplify the exponents

=4-2(-5)

Simplify by multiplication

=4-(-10)

=4+10

Simplify by addition

$=\Large\boxed{14}$
