Q. Using long division, perform the operation below.\newline(a664b6)÷(a2b)(a^{6}-64b^{6})\div(a-2b)
  1. Set Up Long Division: First, set up the long division by writing the dividend a664b6a^6 - 64b^6 and the divisor a2ba - 2b.
  2. Divide First Terms: Divide the first term of the dividend, a6a^6, by the first term of the divisor, aa, to get the first term of the quotient, a5a^5.
  3. Multiply and Subtract: Multiply the entire divisor (a2b)(a - 2b) by the first term of the quotient a5a^5 to get a62a5ba^6 - 2a^5b.
  4. Divide New Dividend: Subtract the result a62a5ba^6 - 2a^5b from the dividend a664b6a^6 - 64b^6 to get the new dividend. Since a6a^6 cancels out, we are left with 2a5b64b62a^5b - 64b^6.
  5. Repeat Division Steps: Divide the first term of the new dividend, 2a5b2a^5b, by the first term of the divisor, aa, to get the next term of the quotient, 2a4b2a^4b.
  6. Complete Division: Multiply the entire divisor (a2b)(a - 2b) by the new term of the quotient (2a4b)(2a^4b) to get 2a5b4a4b22a^5b - 4a^4b^2.
  7. Complete Division: Multiply the entire divisor (a2b)(a - 2b) by the new term of the quotient (2a4b)(2a^4b) to get 2a5b4a4b22a^5b - 4a^4b^2. Subtract the result (2a5b4a4b2)(2a^5b - 4a^4b^2) from the new dividend (2a5b64b6)(2a^5b - 64b^6) to get the next new dividend. Since 2a5b2a^5b cancels out, we are left with 4a4b264b64a^4b^2 - 64b^6.

Divide the first term of the next new dividend, (2a4b)(2a^4b)77, by the first term of the divisor, aa, to get the next term of the quotient, (2a4b)(2a^4b)99. Multiply the entire divisor (a2b)(a - 2b) by the new term of the quotient 2a5b4a4b22a^5b - 4a^4b^211 to get 2a5b4a4b22a^5b - 4a^4b^222. Subtract the result 2a5b4a4b22a^5b - 4a^4b^233 from the next new dividend 2a5b4a4b22a^5b - 4a^4b^244 to get the next new dividend. Since (2a4b)(2a^4b)77 cancels out, we are left with 2a5b4a4b22a^5b - 4a^4b^266. Divide the first term of the next new dividend, 2a5b4a4b22a^5b - 4a^4b^277, by the first term of the divisor, aa, to get the next term of the quotient, 2a5b4a4b22a^5b - 4a^4b^299. Multiply the entire divisor (a2b)(a - 2b) by the new term of the quotient (2a5b4a4b2)(2a^5b - 4a^4b^2)11 to get (2a5b4a4b2)(2a^5b - 4a^4b^2)22. Subtract the result (2a5b4a4b2)(2a^5b - 4a^4b^2)33 from the next new dividend (2a5b4a4b2)(2a^5b - 4a^4b^2)44 to get the next new dividend. Since 2a5b4a4b22a^5b - 4a^4b^277 cancels out, we are left with (2a5b4a4b2)(2a^5b - 4a^4b^2)66. Divide the first term of the next new dividend, (2a5b4a4b2)(2a^5b - 4a^4b^2)77, by the first term of the divisor, aa, to get the next term of the quotient, (2a5b4a4b2)(2a^5b - 4a^4b^2)99. Multiply the entire divisor (a2b)(a - 2b) by the new term of the quotient (2a5b64b6)(2a^5b - 64b^6)11 to get (2a5b4a4b2)(2a^5b - 4a^4b^2)66. Subtract the result (2a5b64b6)(2a^5b - 64b^6)33 from the next new dividend (2a5b64b6)(2a^5b - 64b^6)33 to get the next new dividend. Since both terms cancel out, we are left with (2a5b64b6)(2a^5b - 64b^6)55, and the division is complete.
