Hi,
x^2-x-30 = (x +5)(x-6) Might recommend a pattern of placing the + in 1st parenthesis
think of Using FOIL in your decision as to the placement of the minus sgn
F	First terms
O	Outside terms  -6x
I	Inside terms    5x
L	Last terms
or (either way..)
x^2-x-30 = (x-6)(x+5)
F	First terms
O	Outside terms   5x
I	Inside terms    -6x
L	Last terms
