X^2-4x-45. Factor it to find x. The product of 1 and -45 is -45. Use product sum method to get X^2-9x+5x-45. Now factor by grouping. x(x-9)+5(x-9). You then get (x+5)(x-9)=0 Now use zero product property x+5=0 and x-9=0 and you get x=-5 and x=9.

you should get the same answer when you foil it using the FOIL method.
FOIL method is first, outer, inner, last (multiply). I hope it helps!
