Answer:
Step-by-step 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:
[tex] {x}^{2} - 6x - 27[/tex]
Step-by-step explanation:
[tex](x + 3) \times (x - 9)[/tex]
[tex]x(x−9)+3(x−9)[/tex]
[tex]x \times x+x(−9)+3(x−9)[/tex]
[tex] {x}^{2} +x(−9)+3x+3(−9)[/tex]
[tex] {x}^{2} −9x+3x−27[/tex]
[tex] {x}^{2} - 6x - 27[/tex]
