Does (a) go like this?
2x isnt involved in the expanding part because it is not attached to (5-x^2)
you use it for the simplify part tho

Also note that $x^3+x^3=2x^3$, not $x^6$

also you dont need to draw the curved lines at the start
its no biggie but it can waste time when you have to factorise more stuff

For (b)
I have to expand just 2 brackets first right?

Your terms should all be in paranthsesis
The ones you got from the product of two factors
thick storm
I dont really get it

@thick storm think of it like this $(a+b)(c+d)(e+f)$. When using two brackets only, write it as $(a+b)(c+d)$. Now you get some terms in the big bracket $x+y+z$
