|
Answer» Let's factorize 539 by LCM. 11 | 539 7 | 49 7 | 7 | 1 539 = 11 X 7² 11 x 7² multiplied by 11 gives 11² x 7² = (11 x 7)² = 77². ∴ 11 is the smallest number by which 539 is multiplied to get a perfect square as the product. 539 x 11 = 5929 = 77² HOPE this may be helpful.

if one zero of the polynomial 2xsquare – 5x – (2k+1 ) is twice the other, then find both the zeroes and the value of k |
|
Answer» LET, p(X)=2x²-5x-(2k+1)--------(1) Also let, α be one ROOT of (1). Then the other root will be 2α. α+2α=-(-5)/2 ⇒ 3α=5/2 ⇒ α=5/6 Again, α×2α=-(2k+1)/2 ⇒ 2α²=-(2k+1)/2 ⇒ -(2k+1)/2=2×(5/6)² ⇒ -(2k+1)=4×25/36 ⇒ -2k-1=25/9 ⇒ -2k=25/9+1 ⇒ -2k=34/9 ⇒ k=-34/9×1/2 ⇒ k=-17/9 Ans. |
