  1. 2x^2 +4x -10 = 0       (-4 + - (root(4^2 - 42-10)))/2*2   =  
    (-4 + - (root(96)))/4
    (-4 + (root(96)))/4  ≈  1.45
    (-4 -  (root(96)))/4  ≈  -3.45

    27. f(x) = 0 when any of the components that multiply together equal 0 for this function therefore   x -2 = 0    x +3 = 0    x -5 = 0   so   f(x) = 0 when x = 2, -3 or 5 


    28. It looks like it shows you how to do it
