did you try google
Yes and I cant find any math website that can help me with them.
1 Distribute sum groups 5x3(8x3−5x2+8x+9)+3x2(8x3−5x2+8x+9)−5x(8x3−5x2+8x+9)+4(8x3−5x2+8x+9) 2 Distribute 40x6−25x5+40x4+45x3+3x2(8x3−5x2+8x+9)−5x(8x3−5x2+8x+9)+4(8x3−5x2+8x+9) 3 Distribute 40x6−25x5+40x4+45x3+24x5−15x4+24x3+27x2−5x(8x3−5x2+8x+9)+4(8x3−5x2+8x+9) 4 Distribute 40x6−25x5+40x4+45x3+24x5−15x4+24x3+27x2−40x4+25x3−40x2−45x+4(8x3−5x2+8x+9) 5 Distribute 40x6−25x5+40x4+45x3+24x5−15x4+24x3+27x2−40x4+25x3−40x2−45x+32x3−20x2+32x+36 6 Gather like terms 40x6+(−25x5+24x5)+(40x4−15x4−40x4)+(45x3+24x3+25x3+32x3)+(27x2−40x2−20x2)+(−45x+32x)+36 7 Simplify 40x6−x5−15x4+126x3−33x2−13x+36
(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/
that website is good ^
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
that is one ugly answer box! what kind of system is this?
Its called Odysseyware
homer would have loved it i am sure
the last one looks the most annoying want to do that one fast?
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.
sorry can't help you there
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
they have you working on a machine, let the machine do it
how many terms you can write in that box ??
http://prntscr.com/7g5md9 ur answer is not right
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 ??
