Question

How do you use synthetic substitution to find x=-3 for `f(x) = 2x^2-4x+7`?

Answer 1

`f(-3) = -37`
(see below for evaluation using synthetic substitution)

Explanation:

#{: (,"|",,2,,-4,,7,), (-3,"|",,,,-6,,+30,), (,,"--","-----","--","-----","--","-----","--"), (,,,2,,-10,"|",37,"|"), (,,,,,,,"-----",) :}#
