3 secunde stânga problema ta. Dacă ne sustragem 59 6 și 65 ar fi puțin 3 ori da 3. Ne pare rău dacă nu ați înțeles bine ceea ce am spus, dar eu nu vorbesc limba română sau vorbești
You can only add like terms
exg
you can addd
2+4
2x+4x
2x^2+4x^2
2x^3+4x^3
but not
2+4x
2x^2+2x^3
so when adding like terms keep the exponent
4x+2x=6x
4x^3+2x^3=6x^3
(7x^2+4x-7)+(4x^2-6x+4)
get rid of the parenthasees
7x^2+4x-7+4x^2-6x+4
group like terms (x^2 with x^2 x with x, etc)
(7x^2+4x^2)+(4x-6x)+(-7+4)
add like terms
11x^2-2x-3
Answer:
The last one of commutative property of addition since there is no swapping of numbers related with addition.
