Answer:

k = 0

k = - [tex]\frac{9}{7}[/tex]

Step-by-step Explanation

Quadratic Equation​:

7[tex]k^{2}[/tex]=9k = 0

a = 7

b = 9

c = 0

k =  [tex]\frac{-9+-\sqrt{9^{2}-4x7x0 } }{2x7}[/tex]

Simplify:

k = [tex]\frac{-9+-9}{14}[/tex]

Separate Equations:

k = [tex]\frac{-9+9}{14}[/tex]

k = [tex]\frac{-9-9}{14}[/tex]

Solve:

k = 0

k = - [tex]\frac{9}{7}[/tex]
