I factored 3.6x^6+2x^6-2.8x^2+3.2x as; 3.6x^7+2x^6-2.8x^2+3.2x However my answer is incorrect.
The correct answer should be; 0.4x(9x^6+5x^5-7x+8)
How do I get to the correct answer? So that I am able to do similar problems, because every problem that I have factored with decimals I had gotten wrong. I do not have this problem with factoring polynominals without decimals.

  1. I think you mean
    3.6x^7+2x^6-2.8x^2+3.2x
    first take out (1/10) to get rid of decimals
    (1/10)(36x^7+20x^6-28x^2+32x)
    now take out 4x
    (4x/10)(9x^6+5x^5-7x+8)
