Answer 2

(х+3)(х2-3х+9) = х•х² - х •3х + х•9 +3 •х² - 3•3х + 3•9= х³-3х²+9х+3х²-9х+27=х³ +27, тк.к -3х² и +3х² взаимно уничтожаются, а также +9х и -9х уничтожаются тоже

Answer 3

Solution:

To solve the equation (x+3)(x^2-3x+9), we can use the distributive property to expand the expression:

(x+3)(x^2-3x+9) = x(x^2-3x+9) + 3(x^2-3x+9)

Simplifying further:

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

Combining like terms:

= x^3 + 27

Therefore, the solution to the equation (x+3)(x^2-3x+9) is x^3 + 27.
