Question

from the quadratic equation if one root is 3-2√5​

Answer 1

Answer:

complex roots always occur in pairs.

If one root is a+√ x

then other root will be a-√y

one given root= 3-2√5

other root = 3+2√5

sum of roots= 3-2√5 + 3+2√5

=6

product of roots= (3-2√5)*(3+2√5)

=-9

general formula for writing quadratic equations-

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

therefore, required equation is

x^2-6x-9=0

(ans)

Answer 2

Answer:

x² - 6x - 616

this is the better most answer
