What is the value of k, if (1)/(2) is a root of the equation x^(2) + kx- ( 5)/(4) = 0 ?

If (1)/(2) is a root of the equation x^(2)+kx-(5)/(4)=0, then find the value of k.

If 2 is a root of the equation x^4+2x^3-3x^2+kx-4=0 , then k=

If 1/2 is a root of the equation x^2+kx-5/4=0, then find the value of k.

If 1/2 is a root of the equation x^(2)+Kx - 5/4 = 0 , find the value of K.

If x=5 is a root of the equation kx^2-14x-5=0 , then find the value of k .

If x=5 is the root of a equation kx^(2)-14x-5=0, then find the value of K

If 2 is a root of the equation x^(2) + kx +12=0 and the equation x^(2)+kx +q=0 has equal roots, find the value of q.

If x=5 is a root of equation kx^(2)=14x-5=0 , then find the value of k by completing the following activity.
