whats your definition of solve?
OpenStudy (amistre64):
to me; solve would be to distribute each term in the left thru the paranethesis and then comcine like terms
OpenStudy (toxicsugar22):
sorry Find the first three terms of the product in ascending powers
(2-x+3x^2)(3+2x-x^2+2x^4)
OpenStudy (amistre64):
ascending eh...from little power to biggest...
OpenStudy (toxicsugar22):

3 +2x -x^2
* 2 -x +3x^2
--------------
9x^2+0+0
-3x-2x^2+0
6+4x-2x^2

4 - 7x^2 -8x^4 ...had a typo :)
4x^0 = 4
x^2 -8x^2 = 7x^2
-2x^4 -2x^2 -4x^4 = -8x^4
OpenStudy (toxicsugar22):
0k - got it
OpenStudy (toxicsugar22):
thanks
