(3.9x^2-0.05x-6.2)+(0.7x^2+2.6x+8.3)
show work but dont solve
3.9x^2 + 0.7x^2 - 0.05x + 2.6x - 6.2 + 8.3
4.6x^2 + 2.55x - 1.9
again?
since there's no equation, there is nothing to solve.
So, given that we just have an expression, and you don't want to "solve" it, what do you expect us to do? What work do you expect?
