Factorisation/rationalisation || ∞/∞ form question || One standard results

Check the validity of the following compound statement using (i) direct method contrapositive method and (iii) contradiction method If x is a real number such that 4x^(3)+3x=0, " then" x=0

Rationalise (1)/(sqrt(7)-2)

Show that the statement p: If x is a real number such that x^3+4x=0 . then x is 0 is true by(i) direct method, (ii) method of contradiction,(iii) method of contrapositive.
