Answer:
No because whenever you plug in 2 into the x spots your answer is going to come out as positive one not -8.
For this problem, all you would need to do is plug in numbers for x and y into the calculator. However, none of the ordered pair is a solution to the equations. Unless.. I made a mistake.
Solution by completing the square.
-5x^2+20x-17
=-5(x^2-4x)-17
=(-5(x-2)^2+20) -17
=-5(x-2)^2+3
So a=-5, d=-2, e=+3
a+d+e=-5-2+3=-4
