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:
Answer/Solution
2p=r
Steps/Work
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
=> 2p=r
ANSWER:D
2x2-rx+16=0 for this eqn... roots are R3=r/2 R4=-8
As per Question, p/-8=r/-16
=> 2p=r
ANSWER:D
