Question

Add:
(4s^4-3s^3+5s^2+17s-8)+(s^5+9s^3+6s^2-5s+3) + (-7s^4+s^2-7s-4)

anonymous · Answer

ok.. lets add all the like terms together then string 'em all together in the end...

the highest degree is 5 and you only have one of 'em .  

next is 
s^4:  4s^4 + -7s^4 =
s^3: -3s^3 + 9s^3 =
s^2: 5s^2 + 6s^2 + s^2 =
s^1: 17s + -5s + -7s =
s^0: -8 + 3 + -4 =

can you find all these?

anonymous · Answer

s^4:-3s^4
s^3:6s^3
s^2: 12s^2
s^1: 5s
s^0: -9

?

anonymous · Answer

yep... so we string them all together with "+" to get...

anonymous · Answer

descending or ascending order?

anonymous · Answer

s^5 + -3s^4 + 6s^3 + 12s^2 + 5s + -9

but you can just write a "-" whenever you see a "+ -"

descending exponents order...

anonymous · Answer

can you simplify that then without the "+ -" ?

anonymous · Answer

S^5 + -3s^4 + 6s^3 +12s^2 + 5s -9

anonymous · Answer

s^5 - 3s^4 + 6s^3 + 12s^2 + 5s - 9

that's it.. you just forgot the first one... :)
