Use the following for long division x^2+3x+1sqrt 3x^4+7x^3+2x^2+13x+5

In plain text, it is appropriate to express the division using a division bar (/) and parentheses around the numerator and denominator:

(3x^4 + 7x^3 + 2x^2 + 13x + 5) / (x^2 + 3x + 1)

It is best to reserve the square root symbol (√) for an actual square root.

Your quotient is

3x^2 - 2x + 5
