*Hint: When something is reflected across the y-axis, the rule is (-x, y).
So, you would apply that rule to the coordinate of U. All you do is change the x for a negative number and keep the y as is.
Therefore, the answer would be (-2, -2).
Step-by-step explanation:
Well on the left hand side collect the like terms
then see if it is equal to the right side..?
if it's not equal, there is no solution
so.. just expand the binomial, and simplify if any
multiply and distribute and simplify if any
