1.	If one root is negative to other of equation 4x2–8xk–9=0 .find the value of K .
Answer» Comparing f(x) = 4x2\xa0- 8kx - 9 with ax2+bx+c we geta=4; b=-8k and c=-9.Since one root is the negative of the other, let us assume that the roots are p an -p.Sum of the roots, a+(-a)=-b/a= - (-8k) / 40=2kk=0 Hey how r i
