Answer 1

Answer:

Yes,(-3) is a zero of polynomial 2x⁴ + 9x³ + 11x² + 4x - 6.

Step-by-step explanation:

Given:-

2x⁴ + 9x³ + 11x² + 4x - 6 is a polynomial.

To Verify:-

-3 is a zero of polynomial 2x⁴ + 9x³ + 11x² + 4x - 6.

Verification:-

→p(x)=2x⁴ + 9x³ + 11x² + 4x - 6

→p(-3)=2(-3)⁴ + 9(-3)³ + 11(-3)² + 4(-3)-6

→p(-3)=(2×81)-(9×27)+(11×9)-12-6

→p(-3)=162-243+99-18

→p(-3)=(-81)+81

→p(-3)=0
