To find the quotient of the given polynomials, we first need to clarify what we mean by ‘quotient.’ Here, we are looking at the expression:
- Numerator: 6x^4 + 15x^3 + 2x^2 + 10x + 4
- Denominator: 3x^2 + 2
Next, we will divide the numerator by the denominator using polynomial long division. Here’s how:
Step-by-Step Division:
- Divide the first term of the numerator (6x^4) by the first term of the denominator (3x^2), which gives us 2x^2.
- Multiply the entire denominator (3x^2 + 2) by this result (2x^2) giving us 6x^4 + 4x^2.
- Subtract this from the original numerator:
- Now, repeat the process: divide 15x^3 by 3x^2 to get 5x.
- Multiply the denominator by 5x:
- Subtract again:
- Now, divide -2x^2 by 3x^2 to get -2/3.
- Multiply the entire denominator by -2/3:
- Subtract once more:
(6x^4 + 15x^3 + 2x^2 + 10x + 4)
- (6x^4 + 4x^2)
--------------------------------
(15x^3 - 2x^2 + 10x + 4)
(3x^2 + 2) * 5x = 15x^3 + 10x
(15x^3 - 2x^2 + 10x + 4)
- (15x^3 + 10x)
----------------------------------
(-2x^2 + 4)
-2/3 * (3x^2 + 2) = -2x^2 - 4/3
(-2x^2 + 4)
- (-2x^2 - 4/3)
---------------------
(4 + 4/3) = (12/3 + 4/3) = (16/3)
This means the final quotient is:
2x^2 + 5x - 2/3 with a remainder of 16/3
Therefore, the result of dividing 6x^4 + 15x^3 + 2x^2 + 10x + 4 by 3x^2 + 2 yields:
2x^2 + 5x – 2/3 + (16/3)/(3x^2 + 2)
