Question

if x = 3 is a root of the quadratic equation kx^2 - 10 X + 3 = 0 then find the value of k​

Answer 1

Answer:

Solution. So, x = 3 must satisfy the given quadration equation. Thus, k = 3

Answer 2

P(x)=kx²-10x+3. given x=3

Now,

k(3)²-10(3)+3=0

k9-30+3=0

9k=30-3

k=27/9

k=3

here is your answer
