Answer 2

Given,

(x-7)(x-9)

To find,

Multiply (x-7)(x-9)

Solution,

(x-7)(x-9)

First, we would multiply the term x with (x-9) then we would add the multiplication of  -7 with (x-9).

Mathematically,

⇒   x(x-9) -7(x-9)

⇒   x²-9x-7x+63.

-9x and -7x have the same variable term x so they can be further added and we would get,

⇒   x²-16x+63.

After this term can not be further be simplified.

Hence, the multiplication of (x-7)(x-9) is x²-16x+63.
