You can find the answer by using the method of "Factoring" the equation, the factored for will give you "(x-5)^2 =y" which can also be written as "(x-5) + (x-5). Good luck!

Answer:

discriminant = 0

Explanation:

discriminant is b² - 4ac

in this problem, a = 1, b = -10, c = 25

you plug the values of a, b, and c into the discriminant formula: b² - 4ac

(-10)² - 4(1)(25) = 100 - 100 which equals zero
