subtract the following rational expression

b)3x-1/x^2+4x+3 - x+6/2x^2+7x+1

2. are you sure thats the correct equation?

is that denominator of $2x^2 + 7x + 1$ correct?

yes it is right and seems quite odd because it seems unfactorable.

4. lol it is unfactorable.
are you sure its not subtract the following irrational expression?

$
x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}
$

$
x= \frac{-7 \pm \sqrt{7^2 - 4(2)(1)}}{2(2)}
$

$
x = \frac{-7 \pm \sqrt{41}}{4}
$

which is irrational

The questions description is simplify and state restrictions on the variable, the activiy title being subtracting rational expressions, I wrote the question identical to the one from the book
