which of the followin has a solution set of {-5,2}

A)X^2+3X-10=0
B)X^2-3X=10
C)X^2+3X=-10
D)X^2-3X+10

    mmmmh, I guess we should try if the given solution works,
    I will do one of them, B)
    if x= -5, LS = 25 - 3(-5) = 40
    RS = 10 , so NOPE!

    remember if x=-5 would have worked you would still have to check for x=2

    now you try the others.
