    (x^4 + 4x^3 + 2x^2 + x + 4) / (x^2 + 3x)

    x^4 / x^2 = x^2

    2. Now, you will multiply this answer by the denominator:

    x^2 (x^2 + 3x) = x^4 + 3x^3

    (x^4 + 4x^3 + 2x^2 + x + 4)

    -x^4 - 3x^3

    = x^3 + 2x^2 + x + 4

    1. x^3 / x^2 = x

    2. x (x^2 + 3x) = x^3 + 3x^2

    3. x^3 + 2x^2 + x + 4

    -x^3 - 3x^2

    = - x^2 + x + 4

    1. - x^2 / x^2 = - 1

    2. (-1) (x^2 + 3x) = - x^2 - 3x

    3. - x^2 + x + 4

    +x^2 + 3x

    = 4x + 4

    To solve, first rewrite the equation:

    (x^4 + 4x^3 + 2x^2 + x + 4) / (x^2 + 3x)

    1. Then, you will divide the term with the highest power in the numerator (x^4) by the term in the denominator with the highest power (x^2). When exponents are involved in dividing, you simply subtract them from one another:

    x^4 / x^2 = x^2

    2. Now, you will multiply this answer by the denominator:

    x^2 (x^2 + 3x) = x^4 + 3x^3

    3. Next, subtract this answer from the numerator, and bring down the rest:

    (x^4 + 4x^3 + 2x^2 + x + 4)

    -x^4 - 3x^3

    = x^3 + 2x^2 + x + 4

    Now, repeat the steps until you're at the simplest form:

    1. x^3 / x^2 = x

    2. x (x^2 + 3x) = x^3 + 3x^2

    3. x^3 + 2x^2 + x + 4

    -x^3 - 3x^2

    = - x^2 + x + 4

    1. - x^2 / x^2 = - 1

    2. (-1) (x^2 + 3x) = - x^2 - 3x

    3. - x^2 + x + 4

    +x^2 + 3x

    = 4x + 4
