Answer:

SOLUTION STEPS

+−6

Multiply 6 and 8 to get 48.

48+5

−

6×3+1

Add 48 and 5 to get 53.

−

6×3+1

Multiply 6 and 3 to get 18.

−

18+1

Add 18 and 1 to get 19.

−

Least common multiple of 8 and 3 is 24. Convert

and

to fractions with denominator 24.

159

−

152

Since

159

and

152

have the same denominator, subtract them by subtracting their numerators.

159−152

Subtract 152 from 159 to get 7.

Answer:

$\frac{7}{24}$

Step-by-step explanation:

$6 \frac{5}{8} + \bigg( - 6 \frac{1}{3} \bigg ) \\ \\ = 6 \frac{5}{8} - 6 \frac{1}{3} \\ \\ = \frac{6 \times 8 + 5}{8} - \frac{6 \times 3 + 1}{3} \\ \\ = \frac{48 + 5}{8} - \frac{18 + 1}{3} \\ \\ = \frac{53}{8} - \frac{19}{3} \\ \\ = \frac{53 \times 3 - 19 \times 8}{8 \times 3} \\ \\ = \frac{159 - 152}{24} \\ \\ = \frac{7}{24}$

Answer:

2x² + 3x + 4 + (17x + 9) / (x² − 4)

Step-by-step explanation:

Start by setting up the division. Make sure to write all the coefficients, even the zero ones.

x² + 0x − 4 | 2x⁴ + 3x³ − 4x² + 5x − 7

Start by dividing the first term of the dividend (2x⁴) by the first term of the divisor (x²). That's 2x²; it'll be the first term in quotient. Multiply the divisor by 2x²:

2x⁴ + 0x³ − 8x²

Subtract that from the first three terms of the dividend:

3x³ + 4x²

Drop down the next term from the dividend, and start the process all over again.

3x³ + 4x² + 5x

When you finish, the quotient will be 2x² + 3x + 4, and the remainder will be 17x + 9.
