If one root of the equation ax2+bx+c=0 is the reciprocal of the other root, then Aa + b = 0 Ba - b = 0 Ca - c = 0 Db - c = 0Submit Let a>0,b>0andc<0. Then, both the roots of the equation ax2+bx+c=0 View Solution
Let the roots be a/r,a an ar where agt0,rgt1 :. Product of the roots =1 impliesa/r.a.ar=1 impliesa^(3)=1 :.a=1 [ one root is 1] Now roots are 1/4,1 and r. Then 1/r+1+r=-b implies1/r+r=-b-1…..i :'r+1/rgt2 implies-b-1gt2 impliesblt-3[f
Divide both sides of the equation 3ax2+3bx+3c=0 by 3 to get the equivalent equation ax2+bx+c=0 with the same roots. 如果ax2+bx+c=0的根是6和9,那么3ax2+3bx+3c=0的根是( ). A.2和3 B.6和9 C.18和27 D.−2和−3 将等式3ax2+3bx+3c=0的两边除以3,得到与ax2...
