Answer 2

To simplify the expression $(2x - 3)^2 - (3x - 5)^2$, we can use the difference of squares identity:

$a^2 - b^2 = (a + b)(a - b)$

In this case, let $a = 2x - 3$ and $b = 3x - 5$. Then we have:

$(2x - 3)^2 - (3x - 5)^2 = [(2x - 3) + (3x - 5)][(2x - 3) - (3x - 5)]$

Simplify the expressions inside the brackets:

$= (5x - 8)(-x + 2)$

Now, if you want to expand it further, you can use the distributive property:

$= -5x^2 + 10x + 8x - 16$

$= -5x^2 + 18x - 16$

So, $(2x - 3)^2 - (3x - 5)^2 = -5x^2 + 18x - 16$.
