Question

 If one root of the equation x^2 + 12 x - k = 0, is thrice The other find the value of k and find the roots of equation​

Answer 1

Answer:

Solution:

Let α be the one root of the equation.

So, other root=3α

To find:

Value of c=?

Solution:

Sum of roots =

a

−b

, where, b=−12,a=1

⇒α+3α=12

⇒4α=12

⇒α=3

Product of roots =

a

c

⇒α×3α=c

⇒3×3

2

=c

⇒c=27
