Question

if x is equal to 1 and X is equal to 3 under root 2 are the root of quadratic equation X square - 5 x + b equal to zero then find the value of a and b​

Answer 1

Answer:

a = -11/3  and  b = 2

Step-by-step explanation:

x = 2/3 and x= -3

Using k(x^2 - S x + P) = 0, we get,

k{x^2 - (2/3 + 3)x + (2/3 x 3)} = 0

put k=1

final equation : x^2 - (11/3)x + 2 = 0

By comparing it to x^2 + a x + b = 0, we get,

a = -11/3  and  b = 2

Answer 2
