Good morning all my math wizards:) Can someone tell me if I did this right in finding the product? (xy-5)^2 =(x^2)(y^2)-5^2=xy^4-5^2?

Question

Good morning all my math wizards:)  Can someone tell me if I did this right in finding the product? (xy-5)^2 =(x^2)(y^2)-5^2=xy^4-5^2?

hoblos · Answer

the formula says:
(a-b)^2 = a^2 - 2ab + b^2
so
(xy-5)^2 = (xy)^2 - 10xy +25
