if a and b are the zeroes of the polynomial x^2-5x+6=0, then find the value of a+b/ab. About the author Aubrey
1 is the ans Step-by-step explanation: a + b = 5/1 = 5 ab = 6/1 = 6 Now (a – b)^2 = a^2 + b^2 – 2ab = (a + b)^2 -2ab – 2ab = (a + b)^2 -4ab Substituting values, we have : (a – b)^2 = 5^2 – 4*6 = 25 – 24 = 1 So (a – b) = √1 = 1 Reply
1 is the ans
Step-by-step explanation:
a + b = 5/1 = 5
ab = 6/1 = 6
Now (a – b)^2 = a^2 + b^2 – 2ab
= (a + b)^2 -2ab – 2ab
= (a + b)^2 -4ab
Substituting values, we have :
(a – b)^2 = 5^2 – 4*6 = 25 – 24 = 1
So (a – b) = √1 = 1
