Question

find k if x =3 root of equation .?​

Answer 1

Answer:

k=3

Step-by-step explanation:

kx^2-10x+3=0

k(3)^2-10(2)+3=0

9k-30+3=0

9k-27=0

9k=27

k=27/9

k=3

Answer 2

Answer:

3.

Step-by-step explanation:

ATQ,  x = 3 is the root of the equation kx² - 10x + 3 = 0.

{Substituting values}

➵ k ( 3 )² - 10 ( 3 ) + 3 = 0

=   9k - 30 + 3 = 0

=   9k - 27 = 0

=   9k = 27

=   k = $\frac{27}{9}$ = 3

∴ k = 3.
