Answer 3

We can + or - and *or divided the same sentence .
Same sentence are should be have this :
1 . the same words for example x and x are same but x and y are not .
2. have same power for example : x^2 and x^2 . x^5 and x^6 are not same .or x^6 and y^6 are not .
So the sames in this are :
-6x and -5x caz in the both we have x .
So can sum them .
But first we have :
(7x^3-5x+2)-(5^3-4x^2+6x-7)=(7x^3-5x+2)+(-5^3+4x^2-6x+7)
K ?

Okay I'm getting it

Answer 5

So same them :
(7x^3-5x+2)+(-5^3+4x^2-6x+7)=-5x-6x+(7x^3+2)+(-5^3+4x^2+7)=
-11x+(7x^3+2)+(-5^3+4x^2+7)
And for numbers :
-11x+2+7+7x^3+-5^3+4x^2=-11x+9+7x^3+-5^3+4x^2=11x-125+9+7x^3
And the answer is :
11x-125+9+7x^3 = 11x-116+7x^3
Got it ?
Are you sure it is -5^3?
I think it s -5x^3 how ever there is no problem .
