Answer 1

Answer:

x^6+25 ok bye bla blaikojghh

Answer 2

Answer:

(x^2 +3x+5)(x ^2 −3x+5)

Step-by-step explanation:

(x^2)^2+2x^2×5+(5)^2−9x^2

⇒ [(x ^2 )^2 +2x^2 ×5+(5)^2 ]−(3x)^ 2

⇒ (x^ 2 +5) ^2 −(3x)^2

[ Since, a ^2 +2ab+b^ 2 =(a+b)^2 ]

⇒ (x^2 +5+3x)(x^2 +5−3x) [ Since, a^2 −b^2 =(a+b(a−b) ]
