Who knows that answer? 4dx+35ax3
35ax^3 + 4dxThe only thing common between the two is (x), so it will be x(35ax^2 + 4d)
2 unless you give me the opposing side of the equation.
Since X is the only common factor between the two; the answer should be x (35ax squared + 4d). When you work this out, you realize that you come back to the original.
