Question

Product of x+3 and x-9

Answer 1

Explanation:

(x+3)(x-9)

multiply x with whole (x-9) and 3 with (x-9)

=x(x-9)+3(x-9)

multiply the brackets

=x^2-9x+3x-27

add or subtract like terms

=x^2-6x-277 is a required answer

Answer 2

`{x}^(2) - 6x - 27`

Explanation:

`(x + 3) * (x - 9)`

`x(x−9)+3(x−9)`

`x * x+x(−9)+3(x−9)`

`{x}^(2) +x(−9)+3x+3(−9)`

`{x}^(2) −9x+3x−27`

`{x}^(2) - 6x - 27`
