Question

the quadratic equation whose one of the root is (3-√5) is what ​

Answer 1

Step-by-step explanation:

one root = (3-√5)

other root = 3+√5

sum of roots = (3-√5) + (3+√5)

= 6

product of roots = (3-√5) (3+√5)

= (9)^2 -(√5)^2

= 18 - 5

13

general quadratic equation are

x^2-(sum of roots)x+product of roots = 0

x^2 - 6x + 13 = 0
