x^2 - 2x + 2 "X squared minus two X plus 2"

Replace all the x's with -2's

(-2)^2 - 2(-2) + 2 "'Negative two' in parentheses squared minus two times -2 plus two"

(-2)^2=-2 squared=-2*-2=4 "'Negative two' in parentheses squared equals 'negative two' in parentheses squared equals negative two times negative two equals four."
2(-2)=-4 "Two times negative two equals four"

4-(-4)+2 "Four minus negative four plus 2"

4-(-4)=4 - -4 = 8 "Four minus negative four equals four minus minus four equals eight"
8+2=10 "Eight plus two equals ten."
