Question

please sove this ........ ill mark the correct answer brainliest.... the answer is +_ 3 root11 please show with steps​

Answer 1

x-1/2x= 3

squaring on both sides

x²+1/4x²-1=9

x²+1/4x²=10

squaring on both sides

x⁴+1/16x⁴+1/2= 100

x⁴+1/16x⁴=199/2

subtract 2(x²/4x²) or 1/2 on both sides

(because 2x²/4x²=1/2)

x⁴+1/16x⁴-(2x²/4x²) = 198/2

[x² - (1/4x²)]² = 99

x²-1/4x² = +_(√99)

x²-1/4x² = +_ 3√11

I hope this helps you
