Question

One root of the quadratic equation kx2 – 10x + 3 = 0
is 1/3
Complete the following activity,to find the
value of k.
​

Answer 1

Answer:

since one of the zero of the polynomial is 1/3

substitute 1/3 in place of "x" in the polynomial .

so,,,

kx2 -10 x +3 =0

k (1/3)^2 -10(1/3) +3 =0

k/9 -10/3 +3 =0

k/9 -30/9 + 27/9 =0

k - 30 +27 / 9 =0

k - 30 +27 =0

k -3 =O

=> k =3

Answer 2

Step-by-step explanation:

put value of x

k(1/3) - 10(1/3)+3=0

9k - 30 +3=0

9k= 30-3

9k =27

k=3
