5*2+9x-2=0 so, going by BODMAS rule 10+9x-2=0 9x=-10+2 9x=-8 x=-8/9 I think!!

If you mean 9x+x then it is 10x when simplified
21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
22 + y
(7x + 5)(x - 2)

With suitable signs between the terms, yes.
It is an algebraic expression of 3 terms

9x+7
You can just add them together. The answer is 9x.
