In order to solve this, you have to look at the order for each of the variable terms. In this case t is your variablr <span>4<span>t0</span>=4</span>
exponent is 0.
<span>−<span>t1</span>=−t</span>
exponent is 1.
<span>t2</span>
exponent is 2.
So you order them by exponents from least to greatest (ascending).
<span><span>4−t+<span>t2</span></span></span>
