Question

Find the smallest number by which the following numbers can be multiplief or divided to get perfect squares. ​

Answer 1

α,β are the zeroes of x2−(k+6)x+2(2k−1)

i.e, α+β=k+6       ( Sum of roots of quadratic )

and αβ=2(2k−1)    ( Product of roots )

According to question, α+β=21αβ

⇒k+6=22(2k−1)=2k−1

⇒k+6=2k−1

⇒k=7

Hence, the answer is 7...______ :)
