Answer 2

Объяснение:

(2x+3)*(3x+2)-13*(x-1)²=6x²+9x+4x+6-13*(x²-2x+1)=6x²+13x+6-13x²+26x-13=

=-7x²+39x-7.

Answer 3

That looks like an algebraic expression! If you're looking to simplify it, let's start by expanding and simplifying each term:

$(2x + 3)(3x + 2) - 13(x - 1)^2$

First, expand the products:

$(2x + 3)(3x + 2) = 6x^2 + 4x + 9x + 6$

Combine like terms:

$6x^2 + 13x + 6$

Now, expand the square:

$13(x - 1)^2 = 13(x^2 - 2x + 1)$

Distribute the 13:

$13x^2 - 26x + 13$

Now, subtract this from the first part:

$6x^2 + 13x + 6 - (13x^2 - 26x + 13)$

Combine like terms:

$6x^2 + 13x + 6 - 13x^2 + 26x - 13$

Combine like terms again:

$-7x^2 + 39x - 7$

So, $(2x + 3)(3x + 2) - 13(x - 1)^2$ simplifies to $-7x^2 + 39x - 7$.
