Question

If p(x) = x 3 + x 2 + √5x + √5 , then value of p(-√5) is

Answer 1

p(x) = x 3 + x 2 + √5x + √5 To find P(-√5) put x=-√5 p(x) = x 3 + x 2 + √5x + √5 P(-√5)= (-√5)^3 +(-√5)^2+(-√5)√5+√5 P(-√5)= -5√5+5-5+√5 P(-√5)= -6√5

Answer 2

Answer:

p(x)= x³ + x² √5 x+√5,

p(- √5)=(-√5)³+(-√5)²+√5(-√5)+√5

=-5√5+5-5+√5

=-4√5

Step-by-step explanation:

Answer is -4√5
