    48n2+10n-2=0

    m<n

    Correct Answer

    m<=n

    Incorrect Answer

    m>n

    Incorrect Answer

    the relation cannot be determined

    Incorrect Answer
    Explanation:

    10m2+79m+63=0
    10m2 +70m+9m+63=0
    10m(m +7) + 9(m +7)=0
    (m+7) ( 10m+9)=0
    m= -7 , -9/10
    48n2+10n-2=0
    48n2 -6n+ 16n -2=0
    6n( 8n-1) + 2(8n-1)=0
    (8n-1) ( 6n+2)=0
    n= 1/8, -2/6
    Hence n>m
