Answer:
[tex]-9[/tex]
Step-by-step explanation:
[tex](x-3)(x-3)(x-3)[/tex]
[tex](x^2-6x+9)(x-3)[/tex]
[tex]x^3-9x^2+27x-27[/tex]
Therefore, the coefficient of [tex]x^2[/tex] is [tex]-9[/tex].
Answer:
-9
Step-by-step explanation:
=> (x-3)³
=> (x-3)(x-3)(x-3)
=> (x²-6x+9)(x-3)
=> x³-3x²-6x²+18x+9x-27
=> [tex]x^3-9x^2+27x-27[/tex]
So, the coefficient of x² is -9
