Question

solve quadratic equation 7 x + 1 by 7 x + 5 = 3 X + 1 by 5 x + 1​

Answer 1

Answer:

$7x + \frac{1}{7x} + 5 = 3x + \frac{1}{5x} + 1$

(49x² + 1 + 35x)5x = 7x(15x² + 1 + 5x)

245x³ + 5x + 175x² = 85x³ + 7x + 35x²

160x³ + 140x² - 2x = 0

Answer 2

(49x² + 1 + 35x)5x = 7x(15x² + 1 + 5x)

49x² + 1 + 35x)5x = 7x(15x² + 1 + 5x)245x³ + 5x + 175x² = 85x³ + 7x + 35x²

49x² + 1 + 35x)5x = 7x(15x² + 1 + 5x)245x³ + 5x + 175x² = 85x³ + 7x + 35x²160x³ + 140x² - 2x = 0
