Step-by-step explanation:

Hey, um, I dont know if ur still doing the whole stop the hackers thing, but there's this one user, echo2155, that I've seen post a link (or a bunch, not sure).

I hope this is what ur looking for, bye!

$2x^2 + 5x + 3 = (2x + 3) (x + 1)$

We have $|ab| = |a||b|$ , so

$|2x^2 + 5x + 3| = |2x + 3| |x + 1| > 0$

Now, both $|2x+3|\ge0$ and $|x+1|\ge0$ (since the absolute value of any number cannot be negative), so we just need to worry about when the left side is exactly zero. This happens for
