Question

If p(x) is a polynomial such that p(-1/2)=0 then a factor of p x
Degree of the polynomial p x =x2( x3+2x+1)

Answer 1

here is your answer

factor of p(x)= x+ 1/2.

degree= 5

Answer 2

Explanation:

Equation is 0 at x=−1

⇒(x+1) is a factor

Quadratic is (x+α)(x+1=0)

p(−2)=2

(−2+α)(−2+1)=2

2−α=2

α=0

Polynomial is

x

+x=0

⇒2
