Given:
x = 2 is a zero of the polynomial 2x² + 3x - p
To find:
The value of p.
Solution:
x = 2 is a zero of the polynomial 2x² + 3x - p
To find the value of p, substitute x = 2 in the given polynomial.
2x² + 3x - p = 0
2 (2)² + 3 (2) - p = 0
2 (4) + 6 - p = 0
8 + 6 - p = 0
8 + 6 = p
p = 14
The value of p is 14
Final answer:
If x = 2 is a zero of the polynomial 2x² + 3x - p then the value of p is 14
