If the ratio of the roots of the equation 4x2-px+8=0 is equal to that of the roots 2x2-rx+16=0, then:
Pick one.
A) 4r=p
B) r=p
C) 2r=p
D) 2p=r
E) None
4x2-px+8=0 for this eqn... roots are R1=p/4 R2=-2   2x2-rx+16=0 for this eqn... roots are R3=r/2 R4=-8   As per Question, p/-8=r/-16   =&gt; 2p=r   ANSWER:2p=r
<result>D</result>
