Verified Answer :

(x - 7)(y - 9)

x(y - 9) - 7(y - 9)

xy - x9 - 7y -7(-9)

xy - 9x - 7y + 63

That's the product.

Answer: \(xy-9x-7y+63\)

Step-by-step explanation:

The given expression: \((x - 7)(y - 9)\)

We know that the distributive property is given by :-

\(a(b+c)=ab+ac\)  [Left side]

\(OR\\\\(b+c)a=ba+ca\)  [Right side]

So applying the distributive property(Left sides) in the above expression, we get

\((x - 7)y - (x - 7)9)\)

Again applying the distributive property (Right side) in the above expression, we get

\(= xy - 7y- 9x +(7)(9)\\\\xy-9x-7y+63\)
