Question

(2) Find k if x = 3 is a root of equation kx² - 10x + 3 = 0.​

Answer 1

Step-by-step explanation:

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

9k - 30 + 3 = 0

9k - 27 = 0

9k = 27

k = 3

Answer 2

Answer:

x= 3 ia a root of equation kx²-10x+3= 0

So, k(3²)-10(3)+3= 0

9k-30+3 = 0

9k-27 = 0

9k= 27

So, k= 3

The value of k is 3
