WebTo perform polynomial synthetic division, here are the steps: Set the divisor to zero to find the number to put in the division box. Express the dividend in standard form. This is the same as writing the dividend in descending order. If the dividend is missing some terms, fill them using zero. WebWell x goes into 3x to the third power 3x squared times. So we'll write it in the x squared place, 3x squared times. Now you might already see your parallel. When we did the synthetic division, we dropped this 3 straight down, and this 3 represented 3x squared. So this 3 and this 3x squared are really representing the same thing.
