Question

if -14 is the Zero of the polynomial P of x is equal to X square + 11 x + k then calculate the value of k​

Answer 1

Answer:

x^2+11x+k

-14^2 +11*-14

196-154

42

Answer 2

The correct answer is -42.

Given: Zero of polynomial = -14.

Equation = $x^{2} +11x+k$.

To Find:  Value of k.

Solution:

If -14 is zero of polynomial then it should satisfy the equation.

$x^{2} +11x+k$ = 0

$(-14)^{2} +11(-14)+k=0$

196 - 154 + k = 0

k = 154 - 196

k = -42

Hence, the value of k is -42.
