Somebody please help me. This Odysseyware program is really stressing me out. :'( 1. Find the sum of (5x3 + 3x2 - 5x + 4) and (8x3 -5x2 + 8x + 9). 2. Add: 2a3 + 5a - 7 and 5a2 - 6a + 12 3. Subtract: 11a2 + 42a - 6 from 14a 2 - 24a + 7. 4. (-6.7x 2 + 2.3x y + 5.2) - (-14.9x 2 - 3.5x y + 7.1)

    (5x^3 + 3x^2 - 5x + 4) + (8x^3 - 5x^2 + 8x + 9)=5x^3 + 3x^2 - 5x + 4 + 8x^3 - 5x^2 + 8x + 9=13x^3 - 2x^2 + 3x + 13

    The answer that it gives is too short for those answers. Or whatever that is.

    usually how you do this is by adding same powers of x together, i.e. \[ 5x^3 + 3x^2 - 5x + 4+8x^3 -5x^2 + 8x + 9=(5x^3+8x^3)+(3x^2-5x^2)+(-5x+8x)+(4+9)=13x^3-2x^2+3x+13\]

    However, if you know how to do these operations, and simply want to save time (or check your answers), you should try http://www.wolframalpha.com/

    sum = add so \[\huge\rm 5x^3 + 3x^2 - 5x + 4 +5a^2 - 6a + 12\] add coefficient of same variables (same degree) combine constant terms

    The answer boxes are all the same for those questions. And I have no idea what to do to get answers that are small enough to fit in the boxes.

    Im stuck on number 9 too. Factor completely, then place the answer in the proper location on the grid. Write the answer in descending powers of x. 6x 4 + 15x 3 y 2 + 3x 2 y 3

    Each question box is different. Sometimes it goes from like 4 boxes to like two rows of boxes. @Nnesha And it doesn't do it itself. I have to figure out the answer and drag the number and symbols to the purple and place them in order. @misty1212

    alright that's right it depends on the answer \[\huge\rm 5x^3 + 3x^2 - 5x + 4 +5a^2 - 6a + 12\] combine like terms what did you get ??
