(3.5 r^2) -5.5 +1.5r^2 +4?
That can be simplified to
5 r^2 -1.5
How would you solve:
3.5r squared minus 5.5 + 1.5r squared plus 4?

(3.5r)^2 or 3.5 r^2 ???
We really need parentheses to see what you mean. I suspect you mean it as
3.5 r^2 -5.5 +1.5 r^2 + 4
you add and subtract like terms, for example you have 3.5 r^2 + 1.5 r^2 which is 5 r^2
and you have 5.5 + 4 = 9.5
