Answer:
x = 4 ±
Step-by-step explanation:
Given
x² - 8x + 3 = 0 ( subtract 3 from both sides )
x² - 8x = - 3
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + 16 = - 3 + 16
(x - 4)² = 13 ( take the square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±

Answer:
Step-by-step explanation:
You are going to integrate the following function:
(1)
furthermore, you know that:
lets call to this integral, the integral Io.
for a general form of I you have In:
furthermore you use the fact that:
by using this last expression in an iterative way you obtain the following:
(2)
with n=2s a even number
for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:
