How do you divide #(x^3+7x^2-4x-1)/(3x-1) #?

Answer 1

#y = 1/3 x^2 + 22/9 x - 14/27 -41/27 frac{1}{3x - 1}#

Divide #x^3# by #3x#, the quotient is #1/3 x^2#
#y = 1/3 x^2 + frac{1/3 x^2 + 7x^2 - 4x - 1}{3x - 1}#
#y = 1/3 x^2 + frac{22/3 x^2 - 4x - 1}{3x - 1}#
Divide #22/3 x^2# by #3x#, the quotient is #22/9 x#
#y = 1/3 x^2 + 22/9 x + frac{22/9 x - 4x - 1}{3x - 1}#
#y = 1/3 x^2 + 22/9 x + frac{-14/9 x - 1}{3x - 1}#
Divide #14/9 x# by #3x#, the quotient is #-14/27#
#y = 1/3 x^2 + 22/9 x - 14/27 + frac{-14/27 - 1}{3x - 1}#

Answer 2

To divide (x^3+7x^2-4x-1) by (3x-1), you can use long division. Here are the steps:

  1. Divide the first term of the numerator (x^3) by the first term of the denominator (3x). The result is (1/3)x^2.

  2. Multiply the entire denominator (3x-1) by the result from step 1, which is (1/3)x^2. This gives you (1/3)x^3 - (1/3)x^2.

  3. Subtract the result from step 2 from the original numerator (x^3+7x^2-4x-1). This gives you (7/3)x^2 - 4x - 1.

  4. Bring down the next term from the original numerator, which is -4x.

  5. Divide the first term of the new numerator ((7/3)x^2) by the first term of the denominator (3x). The result is (7/9)x.

  6. Multiply the entire denominator (3x-1) by the result from step 5, which is (7/9)x. This gives you (7/9)x^2 - (7/9)x.

  7. Subtract the result from step 6 from the new numerator ((7/3)x^2 - 4x - 1). This gives you (-4/9)x - 1.

  8. Bring down the next term from the original numerator, which is -1.

  9. Divide the first term of the new numerator ((-4/9)x) by the first term of the denominator (3x). The result is (-4/27).

  10. Multiply the entire denominator (3x-1) by the result from step 9, which is (-4/27). This gives you (-4/27)x - (-4/27).

  11. Subtract the result from step 10 from the new numerator ((-4/9)x - 1). This gives you (-4/27) + (-4/27).

  12. The final result of the division is (1/3)x^2 + (7/9)x - (4/27).

Therefore, (x^3+7x^2-4x-1)/(3x-1) = (1/3)x^2 + (7/9)x - (4/27).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
