How to solve synthetic division

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. WebThe trick here is this: If, when using synthetic division, I divide by a positive and end up with all positive numbers on the bottom row, then the test root was too high. (This does *not* work in reverse! ... root! And dividing out (that is, dividing out the factor ) leaves me with a quadratic which I can solve, starting by dividing through by ...
