Question

(1-3x)(1-4x+4x+x2)+(3x-1)(1-5x+x2)+3x2

Answer 1

(1-3x)(1-4x+4x+x2)+(3x-1)(1-5x+x2)+3x2=
=(1-3x)(1-4x+4x+x²-1+5x-x²)+3x²=(1-3x)*5x+3x²=5x-15x²+3x²=5x-12x²

Answer 2

I can help you with math problems. It looks like you want me to expand and simplify the following expression:

$$ (1-3x)(1-4x+4x+x^2)+(3x-1)(1-5x+x^2)+3x^2 $$

To do this, I will use the distributive property and combine like terms. Here are the steps:

$$ \begin{aligned} (1-3x)(1-4x+4x+x^2)+(3x-1)(1-5x+x^2)+3x^2 &= (1-3x)(1+x^2)+(3x-1)(1-5x+x^2)+3x^2 \\ &= (1-3x+3x^2-3x^3)+(3x-1-15x^2+x^3)+3x^2 \\ &= -2x^3-11x^2+6x \\ \end{aligned} $$

Therefore, the final answer is:

$$ -2x^3-11x^2+6x $$ Ответь+подробно.+(1-3x)(1-4x+4x+x2)+(3x-1)(1-5x+x2)+3x2
