Product of roots of quadratic equation is (constant term) /(coefficient of x²)
Here,
K/a=1
K=a.
Of you have value of a substitute it.
Hope helps you out!!!
gracymehta30pc9l27:
Can we assume the roots as 1 or -1 that's the only possible two case and bring out the value of k
Because in both the case it is coming out to be 1, so which will be more appropriate to show k=a or k=1?
K=a will be correct because we dont have exact value of a so it will be better to write k=a
Okay thankyouu.
