  • X1 + X2 = -b/a
                  =6/1
                  =6
    X1.X2    = c/a
                  = -5/1
                  =-5

    X1^2 + X2^2 = (X1+X2)^2 - 2.XI.X2
                          = (6)^2 -2.-5
                          = 36+10
                          =46

    Jadi, jawaban nomer 37 itu 46,
    ^2=kuadrat
