Decades since I did this sort of stuff, and I'm clearly not any help to him in this rusty state.
A (line-by-line?) walk-through of the following would be much appreciated - as I can't figure out how to type superscript numbers, I've resorted to ^ instead.
"Simplify 3x^2(2xy + 6x^3y^2)"
I got stumped right at the start (the 3x^2(2xy bit); is it
6x^3y,
6x^3 + 3xy,
or something completely different?
Or should I be solving the bit inside the brackets first?
TIA
