Find the quotient and remainder using long division.

[tex]\[ \frac{-30x^2 + 60x - 38}{5x - 5} \][/tex]

The quotient is [tex]\(\square\)[/tex]

The remainder is [tex]\(\square\)[/tex]



Answer :

To find the quotient and remainder of the division [tex]\(\frac{-30x^2 + 60x - 38}{5x - 5}\)[/tex], we will perform polynomial long division.

### Step-by-Step Long Division Process

1. Setup the Division:

Divide the polynomial [tex]\(-30x^2 + 60x - 38\)[/tex] by the polynomial [tex]\(5x - 5\)[/tex].

2. First Term of the Quotient:

Divide the leading term of the numerator [tex]\(-30x^2\)[/tex] by the leading term of the denominator [tex]\(5x\)[/tex]:
[tex]\[ \frac{-30x^2}{5x} = -6x \][/tex]
So, the first term of the quotient is [tex]\(-6x\)[/tex].

3. Multiply and Subtract:

Multiply [tex]\(-6x\)[/tex] by [tex]\(5x - 5\)[/tex]:
[tex]\[ (-6x) \cdot (5x - 5) = -30x^2 + 30x \][/tex]
Subtract this from the original polynomial:
[tex]\[ (-30x^2 + 60x - 38) - (-30x^2 + 30x) = 30x - 38 \][/tex]

4. Second Term of the Quotient:

Divide the new leading term [tex]\(30x\)[/tex] by the leading term [tex]\(5x\)[/tex]:
[tex]\[ \frac{30x}{5x} = 6 \][/tex]
So, the next term of the quotient is [tex]\(6\)[/tex].

5. Multiply and Subtract:

Multiply [tex]\(6\)[/tex] by [tex]\(5x - 5\)[/tex]:
[tex]\[ (6) \cdot (5x - 5) = 30x - 30 \][/tex]
Subtract this from the current polynomial:
[tex]\[ (30x - 38) - (30x - 30) = -8 \][/tex]

### Conclusion:

No further terms in the numerator are left to divide. Therefore, the process ends here.

- Quotient: The quotient is obtained from the terms we calculated during the process, so it is [tex]\(-6x + 6\)[/tex], which can be simplified as [tex]\([-6.0, 6.0]\)[/tex].
- Remainder: The remainder, which is left after the last subtraction, is [tex]\(-8\)[/tex], which can be written as [tex]\([-8.0]\)[/tex].

Thus, the final results are:

- The quotient is [tex]\((-6x + 6)\)[/tex], which corresponds to [tex]\([-6.0, 6.0]\)[/tex].
- The remainder is [tex]\(-8\)[/tex], which corresponds to [tex]\([-8.0]\)[/tex].

So, the quotient is [tex]\([-6.0, 6.0]\)[/tex] and the remainder is [tex]\([-8.0]\)[/tex].
