1.	Show that (x+4),(x-3) and (x-7) are factors of x^3-6x^2-19x+84.
Answer» BRO first assume f(x) = x^3-6x^2-19x+84 then PUT x=-4 in f(x), if it comes out to be zero then (x+4) is a factor of f(x) SIMILARLY do with the other two FACTORS i.e. (x-3) and (x-7) Step-by-step explanation:

Answer»

BRO first assume f(x) = x^3-6x^2-19x+84

then PUT x=-4 in f(x), if it comes out to be zero then (x+4) is a factor of f(x)

SIMILARLY do with the other two FACTORS i.e. (x-3) and (x-7)
