Question

check whether y-3 is a factor of y^3-2y^2+3y-18 ?

Answer 1

Answer:

yes

Step-by-step explanation:

Let f(y) = y^3-2y^2+3y-18

if y-3 is factor of f(y)

then,f(3) should be equals to 0 i.e, f(y)=0.

Now,putting y= 3 in the given equation

f(3) = (3)^3 - 2*3^2 + 3*3 -18 = 0

hence,(y-3) is a factor of given equation.
