Answer:
Step-by-step explanation:
Apply the quadratic formula. The coefficients are {5, -5, 1}. The discriminant is b^2 - 4ac, which here works out to 25 - 4(5)(1), or 5. This positive result tells us that this quadratic has two unequal, real roots. These roots are:
-(-5) ± √5 5 ± √5
x = --------------- = -------------
10 10
Step-by-step explanation:
can't factor so can use quadratic
5 +/- √(25-20)/10
(5+√5)/10
(5-√5)/10
