If a + b = 5 and ab = 6, find the value of a³ + b³.

If ab + bc + ca = 0

Find the value of 1/(a² - bc) + 1/(b² - ca) + 1/(c² - ab)

If a – b – c = 0, then the value of (a² + b² + c²)/(b + ac) is:

If x + y + z = 10 and x² + y² + z² = 36, then what is the value of x y + y z + z x?

If a + b + c = 15 and ab + bc + ca = 50, then find the value of a² + b² + c².
