subtract the following rational expression
b)3x-1/x^2+4x+3 - x+6/2x^2+7x+1
lol it is unfactorable.
are you sure its not subtract the following irrational expression?
$\displaystyle
x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}
$
$\displaystyle
x= \frac{-7 \pm \sqrt{7^2 - 4(2)(1)}}{2(2)}
$
$\displaystyle
x = \frac{-7 \pm \sqrt{41}}{4}
$
which is irrational
