Answer 1

@triciaal

Answer 2

what is the question?
are you suppose to simplify?

Answer 3

group like terms

Answer 4

simplify by combining like terms

Answer 5

all the x^3 together all the x^2 together all the x together then all the constants together

Answer 6

you write in descending order of the power of the variable

Answer 7

so 11^8+14z

Answer 8

\(3x^3+9z+2x^3+5z+6x^2\)
Take the \(x\) terms and \(z\) terms together
\((4x^3+2x^3+6x^2)+(9z+5z)\)
Then add up anything you can, the \(x^3\) etc.
\((6x^3+6x^2)+(14z)\)
Then you could take out \(6x^2\) as common:
\(6x^2(x+1)+14z\)
Can't see anything more to do
