Question 189172: Please help! I just started this class and it has been over thirty years. Could you check them over please!
1. (y-2)(y2^+2y+4) ___
Type the terms in descending order
(My Answer) y2-8
2. (x^6-11x 3^ +30) divide (x 3^-5)
3. (x 8^-3) + (x 8^ + 3)
Simplify your answer
( My answer) x16^

4. (x5^+4)(x+6)
Type the term in descending order)
( My answer)x6^ +6x5+4x+24

1. (y-2)(y2^+2y+4)
I think you're supposed to multiply these, and put the result in descending order of exponents.
(y-2)(y2^+2y+4)
= y%5E3+-+8
----------------
Type the terms in descending order
(My Answer) y2-8 close, exponent 3 tho.
-----------------
2. (x^6-11x 3^ +30) divide (x 3^-5)
%28x%5E6+-+11x%5E3+%2B+30%29%2F%28x%5E3+-+5%29
= x%5E3+-+6
----------------
3. (x 8^-3) + (x 8^ + 3)
If it's a plus sign, it's 2x^8.
If you meant to multiply, it's
x^16 - 9
----------------
Simplify your answer
( My answer) x16^
------------------
4. (x5^+4)(x+6)
= x%5E6+%2B+6x%5E5+%2B+4x+%2B+24
-------------------------------
Type the term in descending order)
( My answer)x6^ +6x5+4x+24
Same answer, mine's neater tho.
-------------------
Your notation isn't always clear. Use x^6 for x to the 6th power, etc.
