Question

Check whether x=3 is a zero of the polynomial p(x)=x3-3x2+4x-12

Answer 1

Answer:

-9

Step-by-step explanation:

p(3)=(3)3-3(3)2+4(3)-12

=9-18+12-12

=9-18

=-9

Answer 2

1. Step-by-step-explanation :-

↣ P(x) = x³ - 3x² + 4x - 12

x = 3

• p(3) = (3)³ - -3(3)² + 4(3) - 12

• p(3) = 27 - 27 + 12 -12

• p(3) = 0

Hence, x=3 is not the zero of the polynomial [ p(x) = x³ - 3x² + 4x - 12 ]
