If f(x)=2x^49x^3+6x5, then use synthetic division to find f(6)
What is synthetic division? How do I solve this?

Hmmmm. I don't see how synthetic division can help on this. f(6) is just plug in 6 for x and grind.
Synthetic division helps dividing polynomials, which is not here .

....2 3 18 114 679
It is so hard to line things up properly,
in the last two rows, the 3 is under the 12, 18's line up, 108 and 104 line up.
the answer is the last number, namely 679
