Question

find k if x= 3 is a root of equation kx^2 - 10x - 3 =0
plz follow me and answer this question ​

Answer 1

Step-by-step explanation:

ANSWER

Given,

x=3 is one root of the equation kx2−10x+3=0

implies that, the root should satisfy the equation

k(3)2−10(3)+3=0

9k−30+3=0

9k=27

∴k=3

Answer 2

Answer:

Given,

x=3 is one root of the equation kx

2

−10x+3=0

implies that, the root should satisfy the equation

k(3)

2

−10(3)+3=0

9k−30+3=0

9k=27

∴k=3
