Question

if x+1 is a factor of p(x)=kx^2-x-4 find the value of k plz answer fast​

Answer 1

Answer:

hope this helps. k=3

Above is the answer

Answer 2

Step-by-step explanation:

If (x+1) is a factor of function p(x) , then if we put x+1=0 i.e. x=-1 to the function p(x), then p(x) should become zero{This is called the remainder theorem.}

||| Remainder Theorem

If (x-r) is a factor of p(x), then p(r)=0 |||

Therefore, p(-1)=0

k(-1)^2-(-1)-4=0

k = 3 ans.
