Find the value of c so that (x − 4) is a factor of the polynomial f(x). cx^3-4x^2+2x+3
+128407 Find the value of c so that (x − 4) is a factor of the polynomial f(x). cx^3-4x^2+2x+3
If x - 4 is a factor, then 4 is a root...so
c(4)^3 - 4(4)^2 + 2(4) + 3 = 0
64c - 64 + 8 + 3 = 0
64c - 53 = 0
64c = 53
c = 53/64
