Question

If (x-1) is a factor of f (x) = X2 + x + K, then find the value of K​

Answer 1

Answer:

A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.
