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

    you write in descending order of the power of the variable

    \(3x^3+9z+2x^3+5z+6x^2\) 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

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

    @Ahsome your 4x^3 should be 3x^3 and when you simplify you get rid of parenthesis
