Question

Multiply and simplify: 5x^6 ( − 6x^12 − 9x^8 − 2x^5 )

Answer 1

Answer: 5x^11 * (−6x^7 − 9x^3 − 2)

Explanation:

5x^6 * (−6x^12−9x^8−2x^5)=

5x^6 * x^5 * (−6x^(12-5) − 9x^(8-5) − 2x^(5-5))=

5x^6 * x^5 * (−6x^7 − 9x^3 − 2x^0)=

5x^(6+5) * (−6x^7 − 9x^3 − 2(1))=5x^11 * (−6x^7 − 9x^3 − 2)
