hi SlowlyFading,

Sorry to hear about your troubles. I've been away for a few days so I hope this help is not coming too late for you.

What I suggest is you copy the part answers I've shown here and try to fill in the gaps.

Post back all the lines of your answers and I'll check those before we move on to the remainder.

? shows something is missing.

Q1.

Multiply both terms in the bracket by 3x

Now simplify each term.

Q2.

Multiply both terms in the bracket by -6x^2

Now simplify each term.

Q3.

(You can simplify the terms in the bracket first, but, looking at the other questions, I think it best to stick to the general method here.)

Divide each term by 3x

Simplfy each term.

Hope that helps,

Bob
