x^2+8xy-33y^2 = x^2-11xy+3xy-33y^2 = x(x-11y)-3y(x-11y) =
= (x-11y)(x-3y)
x^2-14xy+24y^2 = x^2-12xy-2xy+24y^2
= x(x-12y) - 2y(x-12y)
= (x-12y)(x-2y)
x^2 + 22x +121 = x^2 + 11x + 11x + 121
= x(x + 11) + 11(x + 11)
= (x + 11)(x + 11)
= (x + 11)^2
x^2 - 16x + 39 = x^2 -13x -3x + 39
= x(x - 13) - 3(x - 13)
= (x - 13)(x - 3)
