Given:
1) kt²+2t+3k=0....... (Quadratic Equation)
2) Sum of the Zeroes=Product of the zeroes
To Find:
Value of k= ?
Solution:
kt²+2t+3k=0................ (Given)
Comparing the above equation with
ax²+bx+c=0...... (General form of quadratic eq.)
So, a= k, b= 2 and c=3k
Therefore,
Sum of the roots= -b/a= -2/k
Product of the roots= c/a= 3k/k=3/1
As per the given,
Sum of the zeroes/roots=Product of zeroes
→ -2/k= 3
→ -2=3×k
→ -2=3k
→ k= -2/3
So the value of k is -2/3
Please Write your second question clearly then I can able to solve it.
