Question

please help me to do these​

Answer 1

Answer:

K is 33

Step-by-step explanation:

thats very easy, as long as you understand what is meant by x-1 is the factor

solution

x-1

x=1

f(X)=1

f(x)=x3+6x2-4x-K

substitute the value of X into the equation

f(1)=1^3+6(1)^2-4(1)-k

since the equation is a factor, f(X) is 0

1+36-4-K=0

33=k
