9x^2-24x+k=0

Answer 1

Answer:

I hope the answers are clear

best wishes

Answer 2

Answer:

The given quadratic equation is 9x

2

−24x+k=0, comparing it with ax

2

+bx+c=0 we get,

⇒ a=9,b=−24,c=k

⇒ It is given that roots are real and equal.

∴ b

2

−4ac=0

⇒ (−24)

2

−4(9)(k)=0

⇒ 576−36k=0

⇒ 36k=576

∴ k=16
