Yes.
You can always check by cross multiplying the result.
12 * 12 = 144
12 * - xy = -12xy
12 * xy = 12xy
xy * xy = x^2y^2
Adding together gives you the original 144-x^2y^2

Since 144 - (xy)^2 = 12^2 - (xy)^2 = (12 + xy) (12 - xy) , I trust you are correct.

First pull out the detrimental, as this is way less confusing to artwork with. -(9r^2-eighty one) Then take out the 9. generally i could do the 1st 2 on the comparable time, yet am explaining it in steps. -9(r^2-4) Then element your sq......... -9(r-2)(r+2) try some on your person, that is undemanding as quickly as you get the dangle of it.

144 - x²y²
(12 - xy)(12 + zy)= 144 - 12xy + 12xy - x²y² = 144 - x²y²
