Question

(x+1)(x^2-x+1)-x(x+3)(x-3)​

Answer 1

Ответ:

x^3-x^2+x+x^2-x+1-x^2-3x-x^2+3x=x^3+1-x^2-x^2= x^3-2x^2+1= x(x^2-2x)+1

Answer 2

Ответ:

9x + 1

Объяснение:

(x+1)(x²-x+1)-x(x+3)(x-3)​ = x³+1³ - x(x² - 3²) = x³ + 1 - x³ + 9x = 9x + 1

Answer 3

I can help you with your math problem. To answer in detail, I will expand the brackets and simplify the expression. Here is the solution:

$$ \begin{aligned} (x+1)(x^2-x+1)-x(x+3)(x-3) &= x^3-x^2+x+x^2-x-1-x^3-3x+x^2+3x-x^2+9x\\ &= -x^2+19x-1 \end{aligned} $$

The final answer is $-x^2+19x-1$. I hope this helps.Ответь+подробно.++(x+1)(x^2-x+1)-x(x+3)(x-3)​+
