Question

Show that a+2 is a factor of a³+a²+4​

Answer 1

Step-by-step explanation:

Hey here is the answer of your question

Answer 2

Step by Step Explanation:-

p(a) = a+2

p(0)= 0+2= 2

p(-2)= -2+2= 0

q(a) = a³+a²+4

q(-2)= (-2)³+(-2)²+4

= -8+ 4 +4

= -8+8

= 0

Thus a+2 is a factor of a³+ a²+4
