If α and β are the roots of the equation

If α and β are the roots of the equation 4x² - 19x + 12 = 0, find the equation having the roots 1/α and 1/β

1. 4x² + 19 + 12 = 0
2. 12x² - 19x + 4 = 0
3. 12x² + 19x + 4 = 0
4. 4x² + 19x - 12 = 0
5. None of the above

Given equation is 4x² - 19x + 12 = 0
Let given equation having the roots 1/α and 1/β,
Then required equuation is
12x² - 19x + 4 = 0
