Question

find k if x=3 is a root of kx^2-10x+3=0

Answer 1

Answer:

k=3

Step-by-step explanation:

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

9k-30+3=0

9k=27

k=27/9

k=3

Answer 2

Answer:

k=3

Step-by-step explanation:

Since x=3 is a root, we substitute in place of X

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

9k-30+3=0

9k-27=0

9k=27

k=27/9

k=3
