Equation

Eequation f(x) = 0 has roots x1 = 64, x2 = 100, x3 = 25, x4 = 49. How many roots have equation f(x2) = 0 ?

Result

n =  8

Solution:

y1=8; y2=8 y3=10; y4=10 y5=5; y6=5 y7=7; y8=7 y_{ 1}= 8; \ y_{ 2}= -8 \ \\ y_{ 3}= 10; \ y_{ 4}= -10 \ \\ y_{ 5}= 5; \ y_{ 6}= -5 \ \\ y_{ 7}= 7; \ y_{ 8}= -7 \ \\
