Answer 1

Answer:

 + a is factor of x4 - a2x2 + 3x - 6a Let p(x) = x4 - a2x2 + 3x - 6a we know that if x - α is a factor of p(x) then p(α) = 0 So p( - a) = 0 ( - a)4 ...

Answer 2

➡➡➡➡➡➡➡➡➡➡➡➡➡

➡➡x+a is factor of x

➡4 −a 2x 2 +3x−6a

➡Let p(x)=x 4−a 2 x 2 +3x−6a

➡we know that if x−α is a factor of p(x) then ➡p(α)=0

➡So p(−a)=0

➡

(−a) 4 −a 2 (−a) 2 +3(−a)−a=0

➡a 4−a 4 −3a−a=0

−4a=0

➡a=0
