2022 · 27 Jun · Shift 2 · Q36

JEE MainMathematicsTrigonometric Ratio and IdentitesMCQ+4 / −1
α=sin⁡36∘\alpha = \sin 36^\circα=sin36∘ is a root of which of the following equation?
  1. A
    16x4−10x2−5=016{x^4} - 10{x^2} - 5 = 016x4−10x2−5=0
  2. B
    16x4+20x2−5=016{x^4} + 20{x^2} - 5 = 016x4+20x2−5=0
  3. C
    16x4−20x2+5=016{x^4} - 20{x^2} + 5 = 016x4−20x2+5=0
  4. D
    4x4−10x2+5=04{x^4} - 10{x^2} + 5 = 04x4−10x2+5=0
