Question

give asap the answer of ques​

Answer 1

Answer:

x*²(x*²+5)+9=0

x²+9=0

x²+5=0

x²=-9

x²=-5

x=±3

x=5

Answer 2

x^4 + 5x^2+9
x^4 + 6x^2 - x^2 + 9

x^4 + 6x^2 +9 - x^2
By using identities
(a+b)^2= a^2 + b^2 + 2ab

(x^2+3)^2 -x^2

Identity a^2-b^2=(a+b)(a-b)

(x^2+ 3 + x) (x^2 + 3 - x)
