directrix · Answer

Do you think of synthetic division and synthetic substitution as the same process?

@UnkleRhaukus You good at synthetic substitution. I ain't good at it.

?*

anonymous · Answer

It's just substitution.

anonymous · Answer

x^3+3x^2+4

(-3)^3+3(-3)^2+4=4

anonymous · Answer

No...That's not synthetic substitution @timo86m

anonymous · Answer

I asked you if you were good at SYNTHWTIC substitution, not substitution in general.

anonymous · Answer

Well it says evaluate. You can do it simply by substitution

It says "use synthetic substitution to evaluate", not just "evaluate".  When the problem states the method you are to use, that's not just a suggestion!

I'd never heard of synthetic substitution before, but it appears to be the same concept (Horner's rule) that is used for efficient evaluation of polynomials.
