Answer 3

To evaluate the expression X(2x-1)-3x(3-x) when x=-2, we need to substitute -2 for every occurrence of x in the expression and then simplify:

X(2x-1)-3x(3-x)

= (-2)(2(-2)-1)-3(-2)(3-(-2)) // substitute x=-2

= (-2)(-5)-3(-2)(5)

= 10 - (-30)

= 10 + 30

= 40

Therefore, X(2x-1)-3x(3-x) = 40 when x=-2.
