Question

Q14. If x = 2 is a zero of the polynomial 2x² + 3x – p, then the value of p is *

1 point

-4

0

8

14​

Answer 1

Answer:

Given x = 2 is a solution (zero) of the polynomial 2x²+3x-p

Therefore x=2 satisfies 2x² + 3x - p = 0

Substituting, we get:

8 + 6 - p = 0

p = 14

Answer 2

Answer:

14

Step-by-step explanation:

If

x = 2 is the zero of polynomial,

so,

2x² + 3x - p = 0

=> 2(2)² + 3(2) - p = 0

=> 2(4) + 6 - p = 0

=> 8 + 6 - p = 0

=> 14 - p = 0

=> -p = -14

=> -p × (-1) = (-14)×(-1)

=> p = 14

Hence the value of p = 14
