Question

what is the value of x for which 3 is a root of the equation Kx^2-7x+3=0
​

Answer 1

Answer:

• K = 1

Step-by-step explanation:

• step 1:

put the value of x+3

therefore, k(3)^2 - 7(3) +3=0

• step 2:

multiply them

then ,we will get

k9 - 21 + 3=0

• step 3:

add 3 to -21

then we will get

k9 - 9 =0

• step 4:

take -9 to the LHS

then,

k9 = 0 - 9

k9 =9

• step 5:

take the next 9 to the LHS

therfore,

k = 9/9

then K = 1
