Question

Find the Value of k for which one root of kx square - 14x +8=0 is 2

Answer 1

If root of this equation is (X - 2). then put x is equals to 2 in the given equation.
then by solving we will get K is equals to 5.

Answer 2

Kx^2-14x+8=0

K(2)^2-14(2)+8=0

K4-28+8=0

K4-20=0

K=20/4=5

Therefore value of k=5
