Q:
Which expression is equivalent to 7-2z-4(z^3-z^3+4z^2+11z+14/z+2)?a. -4z^3+4z^2+6z+35b. -4z^3+4z^2-10z-21c. -18z-5d. -18z+10
Accepted Solution
A:
Answer:The answer to your question is: letter AStep-by-step explanation: 7 - 2z - 4(z³ - (z³ +4z² + 11z +14)/z + 2)The result of the division was x² -2x + 7, then 7 - 2z - 4(z³ - z² + 2z - 7) 7 - 2z - 4z³ + 4z² - 8z + 28 -4z³ + 4z² - 10z + 35 Synthetic division 1 4 11 14 -2 -2 -4 -14 1 2 7 0 then = z² - 2z + 7
