Question

$x {}^{4} - 14x {}^{2} + 1$

Answer 1

Answer:

Step-by-step explanation:

x² - 14x + 1

Here a = 1, b = -14, c = 1

By using the quadratic formula,

x = (14 +-√(256-4))/(4)

=> x = (14 +- √252)/4

=> x = (14 +- 6√7)/4

=> x = (7 +- 3√7)/2

Hence x = (7+3√7)/(2)

Also x = (7- 3√7)/(2)

Hope it helps you.
