Question

x^4+1/2x^2 = 5/4 find x

Answer 1

Step-by-step explanation:

x^4+1/2x^2=5/4

A/Q

2x^4+x^2/2=5/4

2x^6=5/4×2

x^6=5/4

x=6√5/4

Answer 2

Answer:

x=2

Step-by-step explanation:

x⁴+1/2x²=5/4

applying componendo and dividendo,

x⁴+1+2x²/x⁴+1-2x²=5+4/5-4

x²+1/x²-1=9/1

(x+1/x-1)²=9

x+1/x-1=√9

x+1/x-1=3

x+1=3(x-1)

x+1=3x-3

3x-x=1+3

2x=4

x=4/2

•°• x=2;

hope it helps.......
