Question

Find a if (x +2) is a factor of p(x) = x2 + x + a.


Please answer fast it’s urgent pleas

Answer 1

Answer:

Given,

g(x)= x+2 =0

x = -2

and p(x) = x ²+x + a

Therefore,

p(-2)= (-2)²+(-2)+a

= 4-2+a = 0

2+a=0

a= -2

Step-by-step explanation:

hope it will help you

Answer 2

Step-by-step explanation:

x + 2 = 0

x = -2

putting the value of x in p(x) we obtain

x² + x + a = 0

(-2)² + (-2) + a = 0

4 - 2 + a = 0

2 + a = 0

a = -2
