Hi Nova
(4u³+6u²+7)+(6u³-2u+7)
= 4u³+6u²+7+6u³-2u+7
Combine like terms
( 4u³+6u³)+(6u²)+(-2u)+(7+7)
= 10u³+6u² -2u+14
There no like terms so you can not simplify the sum
I hope that's help and if you have questions please ask !
Answer:
The difference is 4–3. If you want the difference between 3 and -4, then the difference is 7.
Step-by-step explanation:
I assume the first part of that equation is x^2. -7/2= 3.5 ; 3.5^2=12.25 sooo it should end up as x^2-7x + 12.25. but I might be wrong.
