use long division or synthetic division to find the quotient of (〖2x〗^3 + x^2 + 1 )/(x + 1).

real image below show work

answer:

x   −   1   −   4   divided by x -   1

step-by-step explanation:

1. expand  

2. divide the highest order term in the dividend  

by the highest order term in divisor  

3. multiply the new quotient term by the divisor.

4. the expression needs to be subtracted from the dividend, so change all the signs in  

5. after changing the signs, add the last dividend from the multiplied polynomial to find the new dividend.

6. the final answer is the quotient plus the remainder over the divisor.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
