use synthetic substitution to evaluate the polynomial for the given number x=-3. P(x)=x^3+3x^2+4 P(-3)=
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.
It's just substitution.
x^3+3x^2+4 (-3)^3+3(-3)^2+4=4
No...That's not synthetic substitution @timo86m
I asked you if you were good at SYNTHWTIC substitution, not substitution in general.
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.
