1.	If 1-3 is one root ofthe quadratic equation r2-2kr-6 = 0, then find the value of k2
Answer» Given it's one root of the equation x² - 2kx - 6 = 0 one of its root x = 3 for finding the value of k put the value of x in this equation. (3)² - 2k(3) - 6 = 0 9 - 6k - 6 = 0 6k = 3 k = 3/6 k = 1/2 hence,the value of k = 1/2

If 1-3 is one root ofthe quadratic equation r2-2kr-6 = 0, then find the value of k2

Answer»

Given it's one root of the equation x² - 2kx - 6 = 0

one of its root x = 3 for finding the value of k put the value of x in this equation.

(3)² - 2k(3) - 6 = 0

9 - 6k - 6 = 0

6k = 3

k = 3/6

k = 1/2

hence,the value of k = 1/2
