Question

for what value of k 3 is a zero of the polynomial 2x+x+4

Answer 1

question:

For what value of k, 3 is a root of the polynomial 2x + x + 4 +K

Answer:

To find the the value of k so that 3 is a root of this polynomial

Let's substitute the value of 3 in place of x

2*3 + 3 + 4 +K = 0

=> 6+ 7+K=0

or ,13 + k = 0

or, K = - 13

Thanks for the value of negative 13 the 3 will be the root of this polynomial
