Subtract polynomial (7 + t − 5t2 + 2t3) − (1 + 2t − 4t2 + 5t3)
-3t^3 -t^2-t +6
would you mind showing what steps you took?
yes sure..
7+t -5t^2+2t^3-1-2t+4t^2-5t^3 ( u just have to add or subtract like terms ..., oh and u have to distribute the negative for the second bracket) -5t^3+2t^3-5t^2+4t^2 -2t+t +7-1= (can u do it?)
lol i know ive answered it.. but i just want u to try at least..
\[\large (7 + t - 5t^2 + 2t^3) - (1 + 2t - 4t^2 + 5t^3)\] \[\large 7 + t - 5t^2 + 2t^3 - 1 - 2t + 4t^2 - 5t^3\] \[\large (2t^3- 5t^3)+(- 5t^2 + 4t^2)+(t- 2t)+(7- 1) \] \[\large -3t^3-t^2-t+6\] So \[\large (7 + t - 5t^2 + 2t^3) - (1 + 2t - 4t^2 + 5t^3)=-3t^3-t^2-t+6\]
Thanks
that gives me a good example with the steps so I may practice on others.
