Answer:
Yes, -3 is the zero of given p(x)
Step-by-step explanation:
Given, p(x) = 2x⁴ + 9x³ + 11x² + 4x - 6
Now, p(-3)
= 2 ( -3)⁴ + 9 ( -3)³ + 11 ( -3)² + 4 ( -3) - 6
= 2 × 81 - 9 × 27 + 11 × 9 -12 - 6
= 162 - 243 +99 -18
= 261 - 261
= 0
As, p(-3) = 0 ,
Hence -3 is the zero of the given polynomial. ( Verified)
