Thread: polynomial expressions in standard form

Need some help on these 3

1.) x-6-23x to the 2nd power
2.) Y to the 3rd power - 7y+8+3y to the 3rd power + 7y to the 2nd power -4
3.) 4(T to the 2nd power + 3t -2) - 3(4t -1)

If I understand you correctly, you need to simplify these and put them in standard form.

1)


Put the term with the highest degree on the left-most side and work your way to the right, with the higher degrees to the left:


2)


Combine like terms first:




Now order them:


3)


Multiply it out first:


Combine like terms:
