Question

If and 1 are zeroes of the polynomial 7x2 – 25x + (k−9), then what is the value of k ? please answer fast​

Answer 1

Answer:

The given quadratic equation is x

2

−kx+9=0, comparing it with ax

2

+bx+c=0

∴ We get, a=1b=−k,c=9

⇒ It is given that roots are real and distinct.

∴ b

2

−4ac>0

⇒ (−k)

2

−4(1)(9)>0

⇒ k

2

−36>0

⇒ k

2

>36

⇒ k>6 or k<−6
