Question

Subtract and simplify:

Answer 1

\[1/x^2+5x+6 + 1/x+3 \]

Answer 2

to add fractions, they need to have the same denominator.

for this case, we can either put every term over x^2 and add them or multiply every term by x^2 then add.

the second one is easier. multiplying everything by x^2 gives:

1 + 5x^3 + 6x^2 + x + 3x^2
