Question

show that x=-2 is a zero of the polynomial p(x)=x²+5x+4​

Answer 1

since the remainder is not zero therefore x=-2 is not the zero of given polynomial

Answer 2

Answer:

Step-by-step explanation:

Given that,

p ( x ) = x² + 5x + 4

∴p (- 2 ) = ( - 2 )² + 5 ( - 2 ) + 4

= 4 - 10 + 4 ( ∵ + × - = - )

= 8 - 10

= - 2

Hence, x = - 2 is not a p ( x ).
